Description

Light-receiving component and method for packaging light-receiving component

Technical field

Embodiments of the present disclosure relate generally to the field of optical transmission, and more specifically to a light receiving component and a method for packaging the light receiving component.

Background technique

In traditional light receiving components, a splitter is usually used to divide the optical signal into multiple optical signals. After splitting, each optical signal reaches the corresponding photodetector through the corresponding lens and 45° prism. Among them, you need to assemble the lens with the 45° prism first, and then couple the lens with the splitter. On the one hand, the lens and the 45° prism need to be bonded together with glue, which requires high and difficult bonding processes. Once the bonding process does not meet the requirements, the lens and the 45° prism will be scrapped. On the other hand, if multiple lenses are set up separately, each lens needs to be coupled to the splitter separately. The coupling is difficult and can easily lead to low coupling efficiency, thus affecting the response current of the photodetector.

In summary, traditional light receiving components have shortcomings such as difficulty in lens coupling and difficulty in bonding the lens to the 45° prism.

Accordingly, those of ordinary skill in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the disclosure. Also, descriptions of well-known functions and constructions are omitted from the following description for clarity and conciseness.

As described above, in traditional optical receiving components, the optical signal is transmitted to the splitter through the optical fiber pin, and is divided into multiple optical signals of specific wavelengths by the splitter. Multiple lenses and 45° prisms corresponding to the optical signal turn the transmission direction of the optical signal 90°, and then multiple corresponding photodetectors detect the optical signal of the corresponding optical path. This solution requires the lens and the 45° prism to be bonded together through glue, which requires high and difficult bonding processes. Once the bonding process does not meet the requirements, the lens and the 45° prism will be scrapped. Moreover, multiple lenses are set up separately, and each lens needs to be coupled to a splitter respectively. The coupling is difficult and can easily lead to low coupling efficiency, thus affecting the response current of the photodetector.

In order to at least partially solve one or more of the above problems and other potential problems, example embodiments of the present disclosure propose a light receiving assembly solution. In the present disclosure, the optical splitting component is an integrated structure, which includes a light splitting part and a corresponding lens array part. The light splitting part is used to divide the optical signal from the optical fiber adapter into multiple optical signals for output to the lens array part. Each lens in the plurality of lenses of the lens array part corresponds to each of the multiple optical signals, so as to transmit the corresponding optical signal to the corresponding photodetector. Through the integrated structure of the light splitting component, the multiple lenses of the light splitting part and the lens array part are naturally coupled, and the step of coupling the lenses and the light splitting part can be omitted, which significantly reduces the difficulty of lens coupling.

The light receiving component of the embodiment of the present disclosure will be described in detail below. FIG. 1 shows a partial structural diagram of a light receiving assembly 100 according to an embodiment of the present disclosure. FIG. 2 shows a partial structural diagram of the light receiving assembly 100 according to an embodiment of the present disclosure. FIG. 3 shows a schematic structural diagram of the light splitting component 106 and the displacement prism 122 according to the embodiment of the present disclosure. FIG. 4 shows a schematic structural diagram of the light splitting component 106 and the displacement prism 122 along the Z-axis direction according to the embodiment of the present disclosure. For convenience of explanation, the X-axis, Y-axis, and Z-axis are shown in the figure. The light receiving assembly 100 includes: a tube housing 104, a fiber optic adapter 102, an optical splitting component 106 and a photodetector array 114. The fiber optic adapter 102 is coupled to the tube housing 104 to transmit optical signals to the interior of the tube housing 104 . The optical splitting component 106 is provided inside the package 104 . The optical branching component 106 has an integrated structure. The light branching part 106 includes a light splitting part 108 and a lens array part 110 . Among them, the light splitting part 108 is used to divide the optical signal from the optical fiber adapter 102 into multiple optical signals to output to the lens array part 110 . The lens array unit 110 includes a plurality of lenses 112 . Each lens 112 of the plurality of lenses 112 respectively corresponds to each of the plurality of optical signals, so as to transmit the corresponding optical signal to the corresponding photodetector 116 . The photodetector array 114 includes a plurality of photodetectors 116 for detecting multiple optical signals. The light receiving surface of each photodetector 116 in the plurality of photodetectors 116 is perpendicular to the optical axis of the corresponding lens 112 . In some embodiments, the X-axis, for example, corresponds to the direction in which the length of the tube shell 104 extends, the Y-axis, for example, corresponds to the direction in which the width of the tube shell 104 extends, and the Z-axis, for example, corresponds to the direction in which the height of the tube shell 104 extends.

In some embodiments, the light receiving assembly 100 further includes a displacement prism 122, a spacer 128, and a transimpedance amplifier 130, for example.

In the above solution, through the integrated structure of the light splitting component 106, the light splitting part 108 and the plurality of lenses 112 of the lens array part 110 are naturally coupled, and the step of coupling the lenses 112 and the light splitting part 108 can be omitted, significantly reducing the cost of the lens. The difficulty of coupling is conducive to ensuring the efficiency of optical coupling and ensuring that the response current of the photodetector meets the predetermined requirements. Furthermore, by the light receiving surface of each photodetector 116 in the plurality of photodetectors 116 being perpendicular to the optical axis of the corresponding lens 112, the 45° prism in the traditional light receiving component can be omitted, so that both The optical path is simplified, and the step of pasting the lens and the 45° prism can be omitted, reducing the process difficulty.

The spectroscopic part 108 includes, for example, a spectroscopic part light incident surface 121 and a spectroscopic part light output surface 118 . The light incident surface 121 of the light splitting part is used for allowing the optical signal from the optical fiber adapter 102 to be incident on the light splitting part 108 . The light exit surface 118 of the light splitting part is used for outputting multiple optical signals. It should be understood that the light incident surface 121 of the light splitting part is opposite to the light exit surface 118 of the light splitting part. The light exit surface 118 of the light splitting part is provided with a corresponding film layer at least within a predetermined range of the area where the multi-channel optical signals are output, so as to output optical signals in the corresponding wavelength range and emit optical signals outside the wavelength range to the light splitting part. Light incident surface 121. The light incident surface 121 of the light splitting part reflects the optical signal reflected by the light exit surface 118 of the light splitting part to the light exit surface 118 of the light splitting part, so that the optical signal of the corresponding wavelength is output in the corresponding area of the light exit surface 118 of the light splitting part. In some embodiments, the light splitting part 108 is a parallelogram, and the angle between the incident light signal L1 and the light exit surface 118 of the light splitting part 118 is the included angle θ1. Through different configurations of the angle θ1 between the incident optical signal L1 and the light-emitting surface 118 of the spectroscopic part, the distance between the multiple optical signals output by the spectroscopic part 108 can be adjusted.

The lens array portion 110 includes, for example, a lens array portion light incident surface 120 and a lens array portion light exit surface 111 . It should be understood that the light incident surface 120 of the lens array part is arranged opposite to the light exit surface 111 of the lens array part. The light incident surface 120 of the lens array part is used for allowing the multiple optical signals output by the spectroscopic part 108 to be incident on the lens array part 110 . The light incident surface 120 of the lens array part is perpendicular to the optical axis of each lens 112 of the plurality of lenses, so that the multiple optical signals are incident on the lens array part 110 with higher efficiency. The angle θ2 between the light incident surface 120 of the lens array part and the light exit surface 118 of the light splitting part 108 is an acute angle. That is, a V-shaped groove is formed between the spectroscopic part 108 and the lens array part 110 so that a film layer is provided on the surface of the light-emitting surface 118 of the spectroscopic part 108 . A plurality of lenses 112 are formed on the light incident surface 120 of the lens array part, and the plurality of lenses 112 are arranged in an array. In some embodiments, the plurality of lenses 112 are convex lenses. In some embodiments, the plurality of lenses 112 are evenly distributed. For example, the distance between the optical axes of adjacent lenses 112 is equal, for example, D1=D2=D3. The uniform distribution of multiple lenses 112 facilitates matching with the multiple optical signals output by the spectroscopic part 108 and facilitates the installation of multiple photodetectors 116 .

In some embodiments, the light receiving assembly 100 further includes a displacement prism 122 . The displacement prism 122 is located between the optical fiber adapter 102 and the light incident surface of the light splitting part 108 (ie, the light incident surface 121 of the light splitting part), and is used to transmit the optical signal from the optical fiber adapter 102 to the optical splitting component 106 . The displacement prism 122 includes a first surface 123 and a second surface 124 . The first surface 123 is the surface of the displacement prism 122 close to the optical fiber adapter 102 . The first surface 123 includes a light incident part 125 and a light reflecting part 126 . The light incident part 125 is used for allowing the optical signal from the optical fiber adapter 102 to enter the displacement prism 122 for transmission to the second surface 124 . The reflective part 126 is used to reflect the optical signal reflected by the second surface 124 toward the optical splitting component 106 so that the optical signal is transmitted to the optical splitting component 106 . For example, the reflective part 126 is provided with reflective components (including but not limited to film layers) for reflecting light signals. The second surface 124 is used to reflect the light signal entering the displacement prism 122 through the light incident part 125 of the first surface 123 toward the light reflecting part 126 of the first surface 123 . For example, the second surface 124 is provided with a reflective component (including but not limited to a film layer) for reflecting optical signals. The first surface 123 and the second surface 124 are arranged in contact with each other, and the angle θ3 between the first surface 123 and the second surface 124 is an acute angle.

In the above solution, optical signal displacement can be achieved by displacing the prism 122. In this way, the optical fiber adapter 102 does not have to be aligned with the incident optical path of the optical splitting component 106 (for example, the optical path corresponding to the optical signal L1). This is an optical fiber adapter. The relative position setting between 102 and the optical splitting component 106 provides flexibility and facilitates rational utilization of the internal space of the tube housing 104 . Furthermore, by disposing the first surface 123 and the second surface 124 of the displacement prism 122 in contact with each other, the volume of the displacement prism 122 can be reduced and the internal space of the tube shell 104 can be saved. Moreover, by having the first surface 123 having both the light incident part 125 and the light reflecting part 126, the light signal enters the displacement prism 122, and the light signal reflected by the second surface 124 is reflected out of the displacement prism 122, so that the displacement prism can be reduced in size. 122 in volume, saving the internal space of the tube shell 104.

In some embodiments, the displacement prism 122 is attached to the light incident surface side of the light splitting part 108 . In this way, the position where the displacement prism 122 is attached to the spectroscopic part 108 can be flexibly set according to actual needs.

In some embodiments, the displacement prism 122 and the light splitting part 108 are integrated structures. In this way, there is no other medium between the displacement prism 122 and the spectroscopic part 108, which can improve the efficiency of light transmission between the displacement prism 122 and the spectroscopic part 108.

In some embodiments, the light receiving assembly 100 further includes a first pad 128 and a transimpedance amplifier 130 . The first pad 128 is disposed inside the tube casing 104 for supporting the photodetector array 114 and the transimpedance amplifier 130 . The first pad 128 includes: a first surface and a second surface. The first surface is, for example, a surface facing the plurality of lenses 112 , and the first surface is perpendicular to the optical axis of the lenses 112 . The photodetector array 114 is disposed on the first surface and faces the plurality of lenses 112 . It should be understood that the first pad 128 has a predetermined height along the Z-axis direction, and the height of the plurality of photodetectors 116 of the photodetector array 114 on the first surface matches the plurality of lenses 112 . The second surface is perpendicular to the first surface. The transimpedance amplifier 130 is disposed on the second surface. Each photodetector 116 in the photodetector array 114 is respectively bonded to a transimpedance amplifier 130 .

In the above solution, through the first surface of the first spacer 128, the light receiving surface of each photodetector 116 in the plurality of photodetectors 116 can be made perpendicular to the optical axis of the corresponding lens 112, thereby making multiple The light receiving surface of each of the photodetectors 116 directly receives the light signal from the corresponding lens 112 without the need to set up, for example, a 45° prism, which can not only simplify the optical path, but also eliminate the need to stick the lens and the 45° prism. steps to reduce the difficulty of the process.

In some embodiments, the plurality of lenses 112 are evenly distributed, and the plurality of photodetectors 116 are evenly distributed. In this way, coupling of multiple lenses 112 to multiple photodetectors 116 can be facilitated.

In some embodiments, the light receiving assembly 100 further includes a second pad 129 and a third pad 127 . The second pad 129 is attached to the inner wall of the tube shell 104 and is used to support the third pad 127 and the first pad 128 . The third pad 127 is attached to the second pad 129 , and the optical splitting component 106 is attached to the third pad 127 . The first pad 128 is attached to the third pad 127 . The optical fiber adapter 102 and the tube shell 104 are welded together using laser welding.

The method for packaging a light-receiving component according to an embodiment of the present disclosure will be described below with reference to FIGS. 5 to 8 . This method may be used, for example, to package the light-receiving component 100 . FIG. 5 shows a schematic diagram of a system 500 for implementing a method of packaging a light-receiving component according to an embodiment of the present disclosure. The system 500 includes: a control device 502 and a six-axis displacement platform 504. Figure 6 shows a flowchart of a method 600 for packaging a light receiving component according to an embodiment of the present disclosure. The method 600 may be implemented by the system 500, and the control device 502 may include, for example, the electronic device 900 shown in FIG. 9 to generate the control signal. It should be understood that method 600 may also include additional steps not shown and/or steps shown may be omitted, and the scope of the present disclosure is not limited in this respect.

At step 602, the fiber optic adapter is coupled to the housing. For example, the optical fiber adapter 102 and the tube shell 104 are welded together using laser welding.

At step 604, the photodetector array is mounted to a first predetermined position in the package such that a plurality of photodetectors in the photodetector array faces the fiber optic adapter. In some embodiments, installing the photodetector array to the first predetermined position in the tube casing includes, for example: fixing the spacer block at a third predetermined position in the tube casing; and pasting the photodetector array to the third predetermined position of the spacer block. On the surface. In some embodiments, the second pad 129 is attached to the inner wall of the tube shell 104 , the third pad 127 is attached to the second pad 129 , and the first pad 128 is attached to the third pad. In block 127 , the photodetector array 114 is attached to a first predetermined position on the first surface of the first pad 128 .

At step 606, the optical splitting component is disposed at a second predetermined position in the package. For example, the light splitting component 106 is disposed at a second predetermined position on the third pad 127 so that the plurality of lenses 112 faces the photodetector array 114 and the light incident surface 121 of the light splitting part faces the fiber optic adapter 102 . It should be understood that the second predetermined position is an initial position in which the optical splitting component 106 is disposed in the housing 104, which is generally consistent with the target position of the optical splitting component 106, and usually requires calibration.

At step 608, the optical signal is transmitted into the tube housing using the optical fiber adapter, so that the optical signal is transmitted to the photodetector array through the optical splitting component.

At step 610, response currents of the plurality of photodetectors are obtained at the control device.

At step 612, it is determined whether the response current meets the predetermined condition.

At step 614, if it is determined that the response current does not meet the predetermined conditions, the control device controls the six-axis displacement platform to adjust the position of the optical splitting component until the response current meets the predetermined conditions, so as to fix the optical splitting component when the response current meets the predetermined conditions. location.

At step 616, the optical branching component is fixed at a position where the response current meets the predetermined condition.

For traditional light receiving components, at least two six-axis displacement platforms are needed to adjust the splitter and lens respectively, which makes the control complex and the coupling difficult. In the above solution, through the integrated structure of the optical splitting component, a six-axis displacement platform can be used to adjust the entire optical splitting component to complete the coupling of the optical splitting component and the photodetector array, which is simple to operate. , high coupling efficiency.

FIG. 7 shows a flowchart of a method 700 for determining whether a response current meets a predetermined condition according to an embodiment of the present disclosure. Method 700 may be implemented by system 500. It should be understood that method 700 may also include additional steps not shown and/or steps shown may be omitted, and the scope of the present disclosure is not limited in this respect.

At step 702, it is determined whether the response currents of the plurality of photodetectors are all greater than a predetermined current threshold.

At step 704, if it is determined that the response currents of the plurality of photodetectors are all greater than the predetermined current threshold, the control device determines that the response currents meet the predetermined condition.

At step 706, if it is determined that the response currents of the plurality of photodetectors are not all greater than the predetermined current threshold, the control device determines that the response currents do not meet the predetermined condition.

The control device 502 controls the six-axis displacement platform 504 to adjust the position of the optical branching component 106 and obtains the response currents of the multiple photodetectors 116 in real time. If the response currents of the plurality of photodetectors 116 are not all greater than the predetermined current threshold, the control device 502 determines that the response current does not meet the predetermined condition, and the control device 502 controls the six-axis displacement platform 504 to adjust the position of the optical splitting component 106 . If the response currents of the multiple photodetectors 116 are greater than the predetermined current threshold, the control device 502 determines that the response current meets the predetermined conditions, and the control device 502 controls the six-axis displacement platform 504 to stop adjusting the position of the light splitting component 106 so as to split the light. Road member 106 is fixed in this position. Wherein, when the response currents of the plurality of photodetectors 116 are greater than the predetermined current threshold, it indicates that the position of the optical splitting component 106 meets the installation requirements.

8 shows a flowchart of a method 800 for adjusting the position of an optical splitting component according to an embodiment of the present disclosure. Method 800 may be implemented by system 500. It should be understood that method 800 may also include additional steps not shown and/or steps shown may be omitted, and the scope of the present disclosure is not limited in this respect.

At step 802, it is determined whether the response currents of the plurality of photodetectors are all greater than a predetermined current threshold.

At step 804, if it is determined that the response currents of the multiple photodetectors are not all greater than the predetermined current threshold, the control device controls the six-axis displacement platform to adjust the position of the optical branching component so that the response currents of the multiple photodetectors are greater than the predetermined current threshold. current threshold.

At step 806, the control device controls the six-axis displacement platform to continue adjusting the position of the optical branching component until the response current of at least one photodetector among the plurality of photodetectors attenuates, so as to determine that the response current before attenuation meets the predetermined conditions. .

When the response currents of the plurality of photodetectors 116 are greater than the predetermined current threshold, it indicates that the position of the optical splitting component 106 meets the basic installation requirements. In order to further improve the coupling efficiency, the control device 502 controls the six-axis displacement platform 504 to continue to adjust the position of the optical branching component 106 and to continue to obtain the response currents of the multiple photodetectors 116 in real time. Compared with the position before adjustment, if the response current of any of the photodetectors 116 among the response currents of the plurality of photodetectors 116 does not attenuate between the adjusted new position of the optical branching component 106, it means that the new position The position is not worse than the position before adjustment, and the new position can be used as an alternative position for the target position of the optical splitting component 106 . The control device 502 records the position and the response currents of the corresponding multiple photodetectors 116. Then, the control device 502 controls the six-axis displacement platform 504 to continue adjusting the position of the optical branching component 106 and continues to acquire multiple photodetectors in real time. The response current of the detector 116 is increased until the response current of at least one photodetector 116 of the plurality of photodetectors 116 is attenuated. At this time, the control device 502 determines that the coupling efficiency is lower at the position where the attenuation occurs than at the previous position. Therefore, the control device 502 determines that the position before attenuation (ie, the previous position) is the optimized position of the optical splitting component 106, so as to fix the optical splitting component 106 at the optimized position.

In the above solution, after the position of the optical splitting component 106 meets the basic installation requirements, the position of the optical splitting component 106 is further adjusted to determine a more optimal position, thereby obtaining higher coupling efficiency and improving the optical Receive component performance.

Regarding the installation manner of other components of the light receiving assembly according to the embodiment of the present disclosure, details will not be described again here.
