Description

  The present invention relates to an optical module and a method for manufacturing the same.

  An optical element such as a light emitting element or a light receiving element may be deteriorated in performance by being damaged by an external environment such as dust or moisture. In order to prevent such performance deterioration, a method for hermetically sealing an optical element in a package has been developed. For example, Patent Document 1 discloses a hermetic sealing method in which an adhesive layer and a metal layer are formed so as to cover a photon device on a substrate.

On the other hand, when optically coupling an optical element with another device such as an optical fiber, in order to obtain good coupling efficiency, the relative position between the optical element and the other device in the optical axis direction must be precisely adjusted. For this purpose, it is necessary to make the relative positions of the package housing the optical element and the connector supporting other devices appropriate.

Further, the adhesive 28 may be further provided on the upper surface of the lid member 40 or the like.

2. First, a method for manufacturing an optical module according to this embodiment will be described. 4 to 8 are cross-sectional views showing a method for manufacturing an optical module, and each correspond to the cross-sectional view of FIG.

  (1) First, as shown in FIG. 4, the housing 10 is prepared. Although the material of the housing | casing 10 is not specifically limited, For example, it can consist of a metal and ceramics. For example, the casing 10 may be formed of a single layer or a laminate of green sheets made of unsintered ceramics including alumina, for example, the plate member constituting the base portion 12 and the frame member constituting the frame portion 14. The frame member constituting the frame portion 14 is formed by forming a hole in a green sheet. The green sheet can be processed into a desired shape by a punching die or a punching machine. By adjusting the number of green sheets used in the base portion 12 and the frame portion 14, the size of the housing 10 can be adjusted. Moreover, wiring may be formed on the surface of each green sheet by printing or the like. The housing 10 can be formed by laminating the plate member constituting the base portion 12 and the frame member constituting the frame portion 14 and sintering and integrating them. In addition, you may perform the surface treatment of the upper surface of the frame part 14 of the housing | casing 10 so that the housing | casing 10 and the sealing member 20 mentioned later may adhere | attach easily.

  The first wiring 16 and the second wiring 18 are formed using a conductive material after forming holes in the plate member constituting the base portion 12.

  (2) Next, as shown in FIG. 5, a seal member 20 a is provided on the upper surface of the frame portion 14. The seal member 20 a is provided to join the lid member 40 described later and the housing 10. The seal member 20a is not particularly limited as long as it is a material that joins the housing 10 and the lid member 40, but can be made of a thermoplastic insulating material or a metal material, for example, a preform of a low melting point glass. Can do.

  (3) Next, as shown in FIG. 6, the optical element 30 and the housing 10 are joined. Specifically, the optical element 30 is bonded onto the second wiring 18. First, a bonding member is applied, the optical element 30 is disposed on the upper surface of the bonding member, and die bonding is performed while applying an appropriate load downward. As the joining member, for example, a silver paste can be used.

  After the silver paste as the bonding member is cured, as shown in FIG. 1, wire bonding of the wire 36 is performed using a known method. The wire 36 electrically connects the second electrode 35 formed on the substrate 32 and the first wiring 16.

  (4) Next, as shown in FIG. 7, the lid member 40 and the housing 10 are joined by the seal member 20. Specifically, the lid member 40 is disposed on the seal member 20a, and the seal member 20a is heated while pressing the lid member 40 toward the housing 10. For example, the sealing member 20a can be heated by irradiating a laser beam from above. The seal member 20a is deformed by heating and pressing. When a glass substrate is used as the lid member 40, the adhesion between the seal member 20 and the lid member 40 can be improved by applying low melting point glass as the seal member 20a. Thereby, the lid member 40 and the housing 10 can be joined by the seal member 20.

  (5) Next, the lens-attached connector 50 is attached to the package 11 containing the optical element 30 as described above.

  First, the lens-equipped connector 50 described above is prepared, and the package 11 is sandwiched between the first holding members 102. Here, the first holding member 102 may sandwich the package 11 in the optical axis direction as shown in FIG. 8, or may sandwich the housing 10 in the direction perpendicular to the optical axis.

  The first holding member 102 is provided with a current supply unit 106 for supplying a current to the optical element 30. As shown in FIG. 8, the current supply unit 106 can be a spring probe, for example, and has a probe 108 and a socket 109. The spring probe incorporates a spring in the socket 109, and the length of the probe 108 protruding outside the socket 109 can be changed by this spring. The current supply unit 106 can be connected to the outside by a wire or the like. The first holding member 102 sandwiches the package 11 so that the probe 108 contacts the second wiring 18. As a result, the current supply unit 106 can supply current to the optical element 30. The first holding member 102 further includes a spring probe that contacts the first wiring 16 and the probe, although not shown here.

  In addition, when the package 11 is sandwiched, the thickness of the portion of the first holding member 102 protruding above the lid member 40 in the optical axis direction is preferably thinner than the depth of the second recess 59. Moreover, it is preferable that the planar shape of the part which protrudes on the cover member 40 in the 1st holding member 102 is a shape smaller than the 2nd recessed part 59 shown in FIG.

  Further, the connector 50 with the lens is sandwiched between the second holding members 120. At this time, the lens-attached connector 50 is in a state of supporting the optical fiber 124 via the ferrule 122. Since the lens-equipped connector 50 has the third recess 56 as described above, the second holding member 120 can hold the lens-attached connector 50 by hooking the third recess 56. . Here, the optical fiber 124 is connected to a light amount detection device that detects the light amount at the end opposite to the ferrule 122.

  Next, a current is supplied to the optical element 30 to emit light while changing the relative position between the package 11 and the connector with lens 50. Here, by driving at least one of the first holding member 102 and the second holding member 120, the relative position between the package 11 and the lens-attached connector 50 is changed. At this time, the first holding member 102 can be driven so as to avoid the second recess 59. Since the connector 50 with a lens has the 2nd recessed part 59, the 1st holding member 102 contacts the connector 50 with a lens, even if it is the state which has covered the upper surface of the cover member 40, as shown in FIG. It can be driven so as not to.

  The optical fiber 124 receives the light emitted from the optical element 30 via the lens unit 54 and sends the light to the above-described light amount detection device. The light amount detection device detects the light amount of light received by the optical fiber 124 and determines a fixing position for fixing the lens-equipped connector 50 to the package 11 based on the detected light amount. Specifically, the light quantity detection device determines the position where the light quantity is maximum as the fixed position.

  The 1st holding member 102 and the 2nd holding member 120 drive so that the connector 50 with a lens may be arrange | positioned with respect to the package 11 in the determined fixed position. At this time, the first holding member 102 can arrange the package 11 so as to avoid the second recess 59.

  Note that the first holding member 102 and the second holding member 120 can be driven in all directions of the x-axis direction, the y-axis direction, and the z-axis direction when the optical axis direction is the z-axis direction. Is possible. Therefore, in the method of manufacturing the optical module 100 according to the present embodiment, the lens connector 50 or the package 11 is moved in all the x-axis direction, y-axis direction, and z-axis direction to detect the light amount. can do.

  Next, the lens connector 50 is attached to the package 11 by applying and curing the adhesive 28 between the lens connector 50 and the package 11 while being held in a fixed position.

  The optical module 100 can be manufactured through the above steps.

  In the method for manufacturing the optical module 100 according to the present embodiment, a package for storing the optical element 30 is sandwiched between the first holding members 102. Thereby, even if the package does not have a lead wire protruding downward, the package 11 can be easily held.

  In the method of manufacturing the optical module 100 according to the present embodiment, the lens-equipped connector 50 can be fixed to the package 11 at an appropriate position using the first holding member 102 and the second holding member 120. Thereby, as shown in FIG. 1, the distance between the lens portion 54 and the optical element 30 can be precisely adjusted to the length a. Thus, the controllability of the light path can be improved by precisely adjusting the distance between the optical element 30 and the lens unit 54. Therefore, the optical coupling efficiency between the optical element 30 and an external device such as an optical fiber can be improved.

3. Although the case where the optical element 30 is a light emitting element was demonstrated in the manufacturing method of the optical module concerning this Embodiment, it may replace with this and may be a light receiving element. In this case, the first holding member 102 can include a light amount acquisition unit instead of the current supply unit. The light quantity acquisition unit is connected to the light quantity detection device, can obtain an output from the optical element 30, and can send it to the light quantity detection device. The light quantity acquisition unit can be composed of, for example, a spring probe.

  In the method for manufacturing an optical module according to the present embodiment, the optical fiber 124 is connected to the light amount detection device, but instead, it can be connected to a light source. Light is emitted from the optical fiber 124, and the optical element 30 receives the light and sends it to the light quantity acquisition unit.

  Since the operation of the light quantity detection device, the method for determining the fixed position, and other configurations are the same as in the above-described example, description thereof will be omitted.

  Although the description of the present invention has been described above, the present invention is not limited to the above-described embodiment. For example, the present invention includes configurations that are substantially the same as the configurations described in the embodiments (for example, configurations that have the same functions, methods, and results, or configurations that have the same purposes and results). In addition, the invention includes a configuration in which a non-essential part of the configuration described in the embodiment is replaced. In addition, the present invention includes a configuration that exhibits the same operational effects as the configuration described in the embodiment or a configuration that can achieve the same object.
