Detailed Description
It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application. The present application will now be described in further detail with reference to the accompanying drawings and specific examples.
Referring to fig. 1 and fig. 2, in one aspect, an optical transceiver module 1000 is provided, where the optical transceiver module 1000 includes a package 10, a light source 20, a lens assembly 30, a splitter 40, and a receiver 50. The light source 20 is used to emit an outgoing light beam. The outgoing light beam is converged into a converging light beam by the lens group 30. The splitter 40 is located on a side of the lens assembly 30 remote from the light source 20. Splitter 40 includes a first port 41, a second port 42, and a third port 43. The converging beam enters the splitter 40 from the first port 41 and exits from the third port 43. The incident beam enters the splitter 40 from the third port 43 and exits from the second port 42 onto the receiver 50. The receiver 50 is used to convert the incident beam into an electrical signal.
The light source 20, the lens assembly 30, the splitter 40 and the receiver 50 are packaged in the package 10, so that the optical fiber fusion between the devices is reduced, the package has the characteristics of high integration level, small volume and low cost, the size and the assembly complexity of the optical transceiver module 1000 are greatly reduced, the manufacturing difficulty and the cost of the optical transceiver module 1000 are reduced, and the insertion loss caused by the optical fiber fusion can be reduced. The light source 20 emits an outgoing light beam with a certain divergence angle, and the outgoing light beam is converged by the lens assembly 30 to form a convergent light beam, so that the lens assembly 30 couples the energy of the outgoing light beam into the first port 41 to the maximum extent, thereby improving the coupling efficiency.
The incident beam may be the beam formed by the exit beam returning to the third port 43.
In one embodiment, referring to fig. 1 and fig. 2, the lens assembly 30 includes a collimating lens 31 and a focusing lens 32. The collimator lens 31 serves to collimate the outgoing light beam into a parallel light beam. The focusing lens 32 is located between the collimating lens 31 and the splitter 40. The focusing lens 32 is used to condense the parallel light beams into a condensed light beam.
In the embodiment of the present application, by adding the lens group 30, the outgoing light beam is collimated into a parallel light beam by the collimating lens 31 and propagates, and after the parallel light beam passes through the focusing lens 32, the focusing lens 32 couples energy of the parallel light beam into the first port 41. Since the emergent light beam has a certain divergence angle and is collimated by the collimating lens 31, effective focusing by the focusing lens 32 is facilitated, so that a large displacement tolerance can be obtained, the environmental and mechanical stability of the optical transceiver module 1000 is improved, and the reliability of the optical transceiver module 1000 is improved.
In order to obtain a greater coupling efficiency, in an embodiment, please refer to fig. 2, the light source 20, the optical axis of the collimating lens 31, the optical axis of the focusing lens 32 and the optical axis of the splitter 40 are located on the same plane.
In one embodiment, referring to fig. 2, the optical transceiver module 1000 includes a temperature sensing unit (not shown) and a cooling unit 60. The temperature sensing unit is located inside the package 10. The temperature sensing unit is used for sensing the operating temperature of the light source 20. The refrigeration unit 60 is located within the enclosure 10. The refrigeration unit 60 is used to adjust the operating temperature to a set temperature.
The operating temperature refers to the actual ambient temperature at which the light source 20 is operating. The set temperature refers to a preset ambient temperature. Since the wavelength of the outgoing light beam emitted from the light source 20 may shift with the change of the operating temperature, the wavelength of the outgoing light beam may be unstable. Generally, the operating temperature of the light source 20 is increased during operation, and thus the wavelength of the outgoing light beam is unstable, and the operating temperature of the light source 20 is maintained at the set temperature by the temperature sensing unit and the cooling unit 60, so as to ensure the stability of the output power of the light source 20 and the central wavelength of the outgoing light beam.
For example, the set temperature may be 25 ℃, and if the working temperature is higher than 25 ℃, the temperature is reduced by the refrigeration unit 60 until the working temperature is 25 ℃; of course, if the operating temperature is lower than 25 ℃, the temperature may be raised by the refrigeration unit 60 until the operating temperature is 25 ℃.
In one embodiment, referring to fig. 2, the temperature sensing unit is a thermistor. The refrigeration unit 60 is a semiconductor refrigerator.
Because the thermistor has corresponding resistance under different temperatures, the thermistor is used for sensing the working temperature to form corresponding resistance, the driving circuit can detect the resistance corresponding to the thermistor, and the semiconductor refrigerator is controlled to change the temperature according to the corresponding resistance, so that the working temperature is adjusted to the set temperature.
It should be noted that the semiconductor refrigerator refers to a device for generating cold by using the thermo-electric effect of a semiconductor. The semiconductor refrigerator comprises two metal plates connected by a conductor, wherein one metal plate is increased in temperature and the other metal plate is decreased in temperature after the semiconductor refrigerator is connected with current.
In one embodiment, referring to fig. 2, the optical transceiver module 1000 includes a ceramic substrate 70. The ceramic substrate 70 includes a first end face 70a and a second end face 70b opposite to the first end face 70 a. The light source 20, the lens assembly 30, the shunt 40 and the temperature sensing unit are located on the first end surface 70 a. The second end face 70b is connected to the refrigeration unit 60. The ceramic substrate 70 can not only avoid deformation caused by heating or cooling, so as to avoid the change of the optical path of the optical transceiver module 1000 caused by the position changes of the light source 20, the lens assembly 30, the splitter 40 and the temperature sensing unit, but also has good thermal conductivity, so as to facilitate the transfer of heat energy between the light source 20 and the refrigeration unit 60.
In some embodiments, the lens assembly 30 may be bonded to the ceramic substrate 70. This can ensure the operability of coupling the lens group 30. Specifically, the lens assembly 30 may be attached to the ceramic substrate 70 by ultraviolet light.
In one embodiment, referring to fig. 2, the optical transceiver module 1000 includes a heat conducting plate 80. The heat conductive plate 80 is connected to the ceramic substrate 70. The temperature sensing unit and the light source 20 are disposed on the heat conductive plate 80. The rapid conduction of heat between the light source 20 and the temperature sensing unit and the refrigerating unit 60 is achieved by the heat conductive plate 80.
Specifically, the heat conductive plate 80 is a metal plate. For example, the heat conductive plate 80 may be copper, tungsten copper, or the like.
In some embodiments, the light source 20 may be welded to the thermally conductive plate 80. The lens assembly 30 includes a collimating lens 31 and a focusing lens 32, the collimating lens 31 may be bonded to the heat conducting plate 80, and the focusing lens 32 may be bonded or soldered to the ceramic substrate 70.
In one embodiment, referring to fig. 1, the splitter 40 is a planar optical waveguide splitter. The planar optical waveguide splitter has an equal division effect on the incident light beam, that is, after the incident light beam enters the planar optical waveguide splitter from the third port 43, the optical power of the incident light beam can be equally divided into the first port 41 and the second port 42 through the Y-branch structure of the planar optical waveguide splitter. In addition, the planar optical waveguide splitter also has good directivity, that is, after the outgoing light beam enters the planar optical waveguide splitter from the first port 41, the outgoing light beam passes through the Y-branch structure of the planar optical waveguide splitter, and only a very weak light beam in the outgoing light beam is coupled into the second port 42. Because the first port 41 and the second port 42 are located on the same side, it is also convenient to provide the lens assembly 30 and the receiver 50, so that the structure is more compact, and the volume of the optical transceiver module 1000 is further reduced.
In one embodiment, referring to fig. 1, the optical transceiver module 1000 includes an optical fiber 90 and an optical fiber coupling terminal 100. A portion of the optical fiber 90 is located within the package 10. Fiber-optic coupling terminal 100 is located within package 10. The fiber coupling terminal 100 is used for coupling and connecting the optical fiber 90 and the third port 43. The outgoing light beam is output and the incoming light beam is input through the optical fiber 90, and specifically, the optical fiber coupling terminal 100 is bonded with the planar optical waveguide splitter, so that the size of the optical transceiver module 1000 is further reduced, the assembly process is simplified, the reliability is enhanced, and the maintenance is simple.
In one embodiment, referring to FIG. 1, the tolerance between the spot diameter of the converging beam and the mode field diameter of the first port 41 is A, where-6% A + 6%. That is, the spot diameter of the converging light beam is matched with the mode field diameter of the first port 41, so that the joint loss between the converging light beam and the first port 41 can be avoided, and greater coupling efficiency can be obtained.
Note that the tolerance between the spot diameter of the converging beam and the mode field diameter of the first port 41 means that the difference between the spot diameter of the converging beam and the mode field diameter of the first port 41 is compared with the spot diameter of the converging beam.
It will be appreciated that the first port 41, the second port 42 and the third port 43 may each be single mode optical waveguides. Further, the optical fiber 90 may be a single mode optical fiber. A single mode fiber refers to a fiber that can only transmit light in one mode, the fundamental mode. Mode field diameter refers to the maximum distance between two points where the intensity drops to 1/(e ^2) of the maximum intensity on the axis.
In one embodiment, referring to fig. 1, receiver 50 includes a PIN photo detector diode 51. The PIN photo-detection diode 51 is used to convert the incident beam into a current signal. The incident beam is incident on the photo-sensitive surface of the PIN photo-detection diode 51 and converted into a current signal.
In one embodiment, referring to fig. 1, receiver 50 includes a transimpedance amplifier 52. The transimpedance amplifier 52 is connected to the PIN photodiode 51. The transimpedance amplifier 52 converts the current signal of the PIN photodiode 51 into a voltage signal. A Trans-Impedance Amplifier 52 (TIA) converts a current signal of the receiver 50 into a voltage signal, thereby realizing an amplified output.
Specifically, the PIN photodiode 51 and the transimpedance amplifier 52 are connected by a gold wire.
In some embodiments, the light source 20 includes, but is not limited to, a semiconductor light emitting diode or a laser diode. Further, the light source 20 may be a broadband semiconductor light source, preferably, the light source 20 is a super luminescent diode. The central wavelength of the outgoing beam may be 850nm, 1310nm or 1550 nm.
In one embodiment, the optical transceiver module 1000 is hermetically packaged. In this manner, the components within the housing 10 are protected from moisture or other contaminants outside the housing 10.
Another aspect of the embodiments of the present application provides an optical fiber sensing apparatus, which includes the optical transceiver module 1000 according to any one of the embodiments.
Specifically, the optical fiber sensing device may be an optical fiber gyroscope. For example, when the optical transceiver module 1000 is used in an optical fiber gyroscope, the convergent light beam emitted from the third port 43 propagates along two directions of the circular channel, and if the circular channel itself has a rotation speed, the time required for the convergent light beam to travel along the rotation direction of the circular channel is longer than the time required for the convergent light beam to travel along the opposite direction of the rotation direction of the circular channel. That is, when the annular channel rotates, the optical path of the annular channel changes in different directions of travel relative to the optical path of the annular channel when stationary. With this change in optical path length, the returning incident light beam is received by the receiver 50, and a change in phase difference between the two optical paths, i.e., the angular velocity at which the optical paths rotate, is detected.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
