Description

本発明は、光伝送路と光電素子との間の光結合を行う光モジュール及びこの光モジュールを備えた光コネクタに関するものである。   The present invention relates to an optical module that performs optical coupling between an optical transmission line and a photoelectric element, and an optical connector including the optical module.

光通信用の光モジュールは、光伝送路としての光ファイバと光電変換素子（光電素子）とを光学的に結合させるために使用されるものである。   The optical module for optical communication is used for optically coupling an optical fiber as an optical transmission path and a photoelectric conversion element (photoelectric element).

図９は、このような光モジュールに使用される光半導体装置１００を示すものである。この図９に示す光半導体装置１００は、基板１０１上に発光部としての第１の光電変換素子（半導体チップ）１０２を配置すると共に受光部としての第２の光電変換素子（半導体チップ）１０３を配置し、これらを光透過性材料製の封止体１０４の下部に収容するようになっている。そして、この光半導体装置１００の封止体１０４は、第１の光電変換素子１０２から図９の上方へ向けて発せられた光を図９の水平方向（図中右側方向）へ反射する反射面（空気との境界面）１０５を形成し、その第１の光電変換素子１０２から出射された光を封止体１０４の図中右側の側面１０６から取り出すようになっている。また、この光半導体装置１００の封止体１０４は、図９の右側側面から水平方向（図中左側方向）に向かう光を取り入れ、その水平方向の光を反射面１０５によって図の下方へ向けて反射し、その反射光を第２の光電変換素子１０３に照射するようになっている（特許文献１参照）。   FIG. 9 shows an optical semiconductor device 100 used in such an optical module. In the optical semiconductor device 100 shown in FIG. 9, a first photoelectric conversion element (semiconductor chip) 102 as a light emitting unit is arranged on a substrate 101, and a second photoelectric conversion element (semiconductor chip) 103 as a light receiving unit is arranged. These are arranged and accommodated in the lower part of the sealing body 104 made of a light transmitting material. The sealing body 104 of the optical semiconductor device 100 reflects the light emitted from the first photoelectric conversion element 102 upward in FIG. 9 in the horizontal direction in FIG. 9 (right side in the figure). (Boundary surface with air) 105 is formed, and light emitted from the first photoelectric conversion element 102 is extracted from the right side surface 106 of the sealing body 104 in the drawing. Further, the sealing body 104 of the optical semiconductor device 100 takes in light from the right side surface in FIG. 9 in the horizontal direction (left side in the figure), and directs the light in the horizontal direction downward in the figure by the reflecting surface 105. The light is reflected and the reflected light is applied to the second photoelectric conversion element 103 (see Patent Document 1).

尚、このような光半導体装置１００において、封止体１０４の側面１０６から取り出された光は、図示しない光ファイバによって第１の光電変換素子１０２から離れた位置に光伝送したり、封止体１０４の側面１０６から封止体１０４内部に導入する光は、第２の光電変換素子１０３から離れた位置にある発光部から図示しない光ファイバによって封止体１０４の側面１０６に光伝送することも可能である。また、図９に関連する従来技術としては、例えば、特許文献２に挙げられるものが知られている。   In such an optical semiconductor device 100, the light extracted from the side surface 106 of the sealing body 104 is optically transmitted to a position away from the first photoelectric conversion element 102 by an optical fiber (not shown). The light introduced from the side surface 106 of the sealing body 104 into the sealing body 104 may be optically transmitted to the side surface 106 of the sealing body 104 by an optical fiber (not shown) from a light emitting portion located away from the second photoelectric conversion element 103. Is possible. Moreover, as a prior art relevant to FIG. 9, what is mentioned, for example in patent document 2 is known.

しかしながら、光モジュールは、安全上の問題、受光素子の特性、又は通信規格に適合させるため、伝送する光のパワー（光量）を調整しなければならない場合がある。このような場合、図９に示す従来の光モジュール（光半導体装置１００）は、封止体１０４の側面１０６と図示しない光ファイバとの間に光のパワーを調整するための別部品（フィルタやアパーチャー）を配置しなければならず、部品点数が多くなると共に組み立て工程が増加し、製品コストが嵩むという問題が生じる。しかも、光のパワーを調整するための別部品としてアパーチャーを使用した場合には、発光素子から発せられる光の拡がり角のばらつきの影響を受けて通信規格を満足できない場合を生じる虞がある。   However, the optical module may have to adjust the power (light quantity) of light to be transmitted in order to conform to safety problems, characteristics of the light receiving element, or communication standards. In such a case, the conventional optical module (optical semiconductor device 100) shown in FIG. 9 has another component (such as a filter or a filter) for adjusting the light power between the side surface 106 of the sealing body 104 and an optical fiber (not shown). Apertures have to be arranged, and the number of parts increases, the assembly process increases, and the product cost increases. In addition, when an aperture is used as another component for adjusting the power of light, there is a possibility that the communication standard may not be satisfied due to the influence of variation in the spread angle of light emitted from the light emitting element.

そこで、本発明は、部品点数を増やすことなく、量産性に優れ且つ安価に光のパワー調整を行うことができる光モジュール及びこれを備えた光コネクタを提供することを目的としている。   SUMMARY OF THE INVENTION An object of the present invention is to provide an optical module that is excellent in mass productivity and can perform optical power adjustment at a low cost without increasing the number of components, and an optical connector including the same.

The light reflecting means 12 is formed at the bottom of an upper surface opening hole 22 formed in the upper surface 21 of the right end portion of the holder 3, and is a boundary surface between the holder 3 and air (see FIGS. 5 and 6). In addition, as shown in FIG.3 (b), the shape of the opening edge of the upper opening hole 22 may be square shape, and circular shape may be sufficient as it.

また、光反射手段１２は、図６に詳細を示すように、ホルダ３の軸線６に沿って進行する平行光（図２の矢印ｂ）に直交する平面である第１の透過面部２３と、光電変換素子２から発せられてホルダ３内を図中上方へ向かう平行光（図１の矢印ａ）に直交する平面である第２の透過面部２４と、ホルダ３の軸線６に沿って進行する平行光及びホルダ６内を図中上方へ向かう平行光に４５度の傾斜角度で交差する平面である反射面部２５とを備えている。そして、この光反射手段１２は、反射面部２５の一端側に第１の透過面部２３が位置し、反射面部２５の他端側に第２の透過面部２４が位置し、これら第１の透過面部２３，反射面部２５及び第２の透過面部２４によって等脚台形形状の突起になっており、基準傾斜面（図６中の二点鎖線で示す傾斜面）２６に複数形成されている。その結果、図５及び図６に示すように、上部開口穴２２の底部の断面形状が略ステップ形状になっている。なお、基準傾斜面２６は、ホルダ３の軸線６と光電変換素子２から延びる直線１１の交点に位置し、これらホルダ３の軸線６及び光電変換素子２からの直線１１に対して４５度の傾斜角で交差する仮想の平面である。   As shown in detail in FIG. 6, the light reflecting means 12 includes a first transmission surface portion 23 that is a plane orthogonal to parallel light (arrow b in FIG. 2) that travels along the axis 6 of the holder 3, and Advancing along the second transmission surface portion 24, which is a plane perpendicular to parallel light (arrow a in FIG. 1) emitted from the photoelectric conversion element 2 and traveling upward in the figure in the holder 3, and the axis 6 of the holder 3. The reflecting surface 25 is a plane that intersects the parallel light and the parallel light traveling upward in the figure at an inclination angle of 45 degrees. In the light reflecting means 12, the first transmission surface portion 23 is located on one end side of the reflection surface portion 25, the second transmission surface portion 24 is located on the other end side of the reflection surface portion 25, and these first transmission surface portions. 23, the reflecting surface portion 25 and the second transmitting surface portion 24 form an isosceles trapezoidal protrusion, and a plurality of protrusions are formed on the reference inclined surface (inclined surface indicated by a two-dot chain line in FIG. 6). As a result, as shown in FIGS. 5 and 6, the cross-sectional shape of the bottom of the upper opening hole 22 is substantially stepped. The reference inclined surface 26 is located at the intersection of the axis 6 of the holder 3 and the straight line 11 extending from the photoelectric conversion element 2, and is inclined at 45 degrees with respect to the axis 6 of the holder 3 and the straight line 11 from the photoelectric conversion element 2. It is a virtual plane that intersects at a corner.

このような光反射手段１２の第１の透過面部２３は、光ファイバ１０から発せられた光（ホルダ３の軸線６に沿って図６の図中右側方向へ進行する平行光であり、図１の矢印ｂの光）の一部（図１の矢印ｂ１の平行光）を透過する。また、光反射手段１２の第２の透過面部２４は、光電変換素子２から発せられた光（ホルダ３内を直線１１に沿って図６の上方へ進行する平行光であり、図１の矢印ａの光）の一部（図１の矢印ａ１の平行光）を透過する。また、光反射手段１２の反射面部２５は、光ファイバ１０からの光（図２の矢印ｂで示す平行光）を光電変換素子２に向けて光（図２の矢印ｂ２）を反射するか、又は光電変換素子２からの光（図１の矢印ａで示す平行光）を光ファイバ１０に向けて光（図１の矢印ａ２）を反射する。   The first transmitting surface portion 23 of such a light reflecting means 12 is light emitted from the optical fiber 10 (parallel light traveling in the right direction in FIG. 6 along the axis 6 of the holder 3). Part of light (parallel light of arrow b1 in FIG. 1). The second transmission surface portion 24 of the light reflecting means 12 is light emitted from the photoelectric conversion element 2 (parallel light traveling in the holder 3 along the straight line 11 in FIG. a part of light (parallel light indicated by an arrow a1 in FIG. 1) is transmitted. Further, the reflection surface portion 25 of the light reflecting means 12 reflects light (arrow b2 in FIG. 2) by directing light (parallel light indicated by arrow b in FIG. 2) from the optical fiber 10 toward the photoelectric conversion element 2, or Alternatively, light (parallel light indicated by an arrow a in FIG. 1) from the photoelectric conversion element 2 is directed toward the optical fiber 10 to reflect the light (arrow a2 in FIG. 1).

図７は、本実施形態の光モジュール１の作用を模式化して示す図である。この図７の模式図に示すように、光ファイバ１０から発せられた光ｂは、第１のレンズ部１５によって平行光としてホルダ３内に取り入れられ（図２参照）、ホルダ３の軸線６に沿って進行した後、その一部（ｂ１）が光反射手段１２の第１の透過面部２３を透過して直進し、その残部（ｂ２）が光反射手段１２の反射面部２５によって光電変換素子２側に向けて（真下に向けて）反射され、その反射された平行光が第２のレンズ部２０によって光電変換素子２の受光部１８に収束され、その収束された光（ｂ２）が光電変換素子２の受光部１８に入射する。ここで、光電変換素子２に入射する光の光量（光のパワー）は、ホルダ３に入射した光ファイバ１０からの光の光量をＬ０とし、第１の透過面部２３の面積をＳ１とし、反射面部２５の軸線６方向への投影面積をＳ０とすると、反射面部２５と第１の透過面部２３のメッシュ数にもよるが、Ｌ０×（Ｓ０／（Ｓ０＋Ｓ１））程度となる。光束の強度分布を考慮した形状最適化とメッシュ数が多ければほぼ正確な値が計算できる。すなわち、本実施形態の光モジュール１は、反射面部２５と第１の透過面部２３の面積比によって、光反射手段１２を透過する光（ｂ１）の光量と光反射手段１２で反射される光（ｂ２）の光量がほぼ調整されることになる。   FIG. 7 is a diagram schematically showing the operation of the optical module 1 of the present embodiment. As shown in the schematic diagram of FIG. 7, the light b emitted from the optical fiber 10 is taken into the holder 3 as parallel light by the first lens portion 15 (see FIG. 2), and enters the axis 6 of the holder 3. Then, a part (b1) of the light reflecting means 12 passes through the first transmitting surface portion 23 and goes straight, and the remaining part (b2) of the light reflecting means 12 is reflected by the reflecting surface portion 25 of the photoelectric conversion element 2. The reflected parallel light is reflected toward the side (directly below), and the reflected parallel light is converged on the light receiving unit 18 of the photoelectric conversion element 2 by the second lens unit 20, and the converged light (b2) is photoelectrically converted. The light enters the light receiving portion 18 of the element 2. Here, the amount of light (light power) incident on the photoelectric conversion element 2 is L0, the amount of light incident on the holder 3 from the optical fiber 10, and the area of the first transmission surface portion 23 is S1. Assuming that the projected area of the surface portion 25 in the direction of the axis 6 is S0, it is about L0 × (S0 / (S0 + S1)) although it depends on the number of meshes of the reflecting surface portion 25 and the first transmitting surface portion 23. If the shape optimization considering the intensity distribution of the light beam and the number of meshes are large, an almost accurate value can be calculated. That is, the optical module 1 of the present embodiment has a light amount (b1) that passes through the light reflecting means 12 and light reflected by the light reflecting means 12 (depending on the area ratio between the reflecting surface portion 25 and the first transmitting surface portion 23). The amount of light b2) is almost adjusted.

また、図７の模式図に示すように、光電変換素子２から発せられた光ａは、第２のレンズ部２０によって平行光としてホルダ３内に取り入れられ（図１参照）、直線１１に沿って進行した後、その一部（ａ１）が光反射手段１２の第２の透過面部２４を透過して直進し、その残部（ａ２）が光反射手段１２の反射面部２５によって光ファイバ１０側に向けて（真横に向けて）反射され、その反射された平行光（ａ２）が第１のレンズ部１５によって光ファイバ１０の先端に収束され、その収束された光が光ファイバ１０に入射する。ここで、光ファイバ１０に入射する光の光量（光のパワー）は、ホルダ３に入射した光電変換素子２からの光の光量をＬ１とし、第２の透過面部２４の面積をＳ２とし、反射面部２５の直線１１方向への投影面積をＳ０とすると、反射面部２５と第２の透過面部２４のメッシュ数にもよるが、Ｌ１×（Ｓ０／（Ｓ０＋Ｓ２））程度となる。光束の強度分布を考慮した形状最適化とメッシュ数が多ければほぼ正確な値が計算できる。すなわち、本実施形態の光モジュール１は、反射面部２５と第２の透過面部２４の面積比によって、光反射手段１２を透過する光の光量と光反射手段１２で反射される光の光量がほぼ調整されることになる。 Further, as shown in the schematic diagram of FIG. 7, the light a emitted from the photoelectric conversion element 2 is taken into the holder 3 as parallel light by the second lens unit 20 (see FIG. 1), and along the straight line 11. Then, a part (a1) of the light reflecting means 12 passes through the second transmitting surface portion 24 and goes straight, and the remaining part (a2) is moved to the optical fiber 10 side by the reflecting surface portion 25 of the light reflecting means 12. The reflected parallel light (a2) is converged on the tip of the optical fiber 10 by the first lens unit 15, and the converged light is incident on the optical fiber 10. Here, the amount of light (light power) incident on the optical fiber 10 is L1, the amount of light incident from the photoelectric conversion element 2 incident on the holder 3, and the area of the second transmission surface portion 24 is S2. Assuming that the projected area of the surface 25 in the direction of the straight line 11 is S0, it is about L1 × (S0 / (S0 + S2)) although it depends on the number of meshes of the reflecting surface 25 and the second transmitting surface 24. If the shape optimization considering the intensity distribution of the light beam and the number of meshes are large, an almost accurate value can be calculated. That is, in the optical module 1 of the present embodiment, the amount of light transmitted through the light reflecting means 12 and the amount of light reflected by the light reflecting means 12 are approximately equal to each other depending on the area ratio between the reflecting surface portion 25 and the second transmitting surface portion 24. Will be adjusted.

以上のように、本実施形態によれば、ホルダ３に形成した光反射手段１２の反射面部２５と透過面部（第１の透過面部２３又は第２の透過面部２４）の面積比を変えることにより、光伝送に必要な光量（光のパワー）を調整できるため、光量調整用のフィルタ等の別部品を光路途中に設ける必要がなく、光量調整用の部品点数を増やす必要がない。したがって、本実施形態は、構造の複雑化や組み立て工数の増加を生じることがなく、光量調整が可能な光モジュール１を安価に提供できる。   As described above, according to the present embodiment, by changing the area ratio between the reflection surface portion 25 and the transmission surface portion (the first transmission surface portion 23 or the second transmission surface portion 24) of the light reflecting means 12 formed on the holder 3. Since the amount of light (light power) required for optical transmission can be adjusted, there is no need to provide another component such as a filter for adjusting the amount of light in the middle of the optical path, and there is no need to increase the number of components for adjusting the amount of light. Therefore, this embodiment can provide the optical module 1 capable of adjusting the amount of light at a low cost without causing a complicated structure and an increase in assembly man-hours.

尚、図１又は図２に示す光モジュール１は、例えば、図８に示すように、発光用の光モジュール１又は受光用の光モジュール１として、ハウジング２７内に収容され、光コネクタ２８を構成する。   The optical module 1 shown in FIG. 1 or FIG. 2 is housed in a housing 27 as a light emitting optical module 1 or a light receiving optical module 1 as shown in FIG. To do.
