Description

47th Electronic Components and Technology Conference 1997 pp.620-625（文献２）には、ＷＤＭ機能を有する光導波路基板と光電変換素子をレセプタクル型パッケージに納めた光伝送モジュールが記載されている。光導波路はマッハツェンダ型光結合器を有し、１．３μｍと１．５５μｍの光の合分波を実現している。光電変換素子はそれぞれ別の基板に実装され、光導波路基板と光電変換素子を実装した基板をセラミックパッケージ内で位置決め固定することにより光導波路と光電変換素子を光接続している。光ファイバは素線の片端にフェルールを取りつけたフェルール付き光ファイバ構造とし、素線部分をファイバホルダで光導波路基板に取り付け、フェルールをブロックで保持固定している。ブロックによるフェルール保持部が第２の光ファイバとの着脱を可能としている。また、水分、酸素等による光電変換素子の腐食及び光結合部への結露を防ぐために、セラミックパッケージに蓋を被せ、接着固定して光結合部の気密封止を実現している。セラミックパッケージから伸びたフラットリードをリフローハンダ付けすることにより、プリント配線基板への実装を可能としている。
特開平１１−１１９０６４号公報 The 47th Electronic Components and Technology Conference 1997 pp.620-625 (Reference 2) describes an optical transmission module in which an optical waveguide board having a WDM function and a photoelectric conversion element are housed in a receptacle type package. The optical waveguide has a Machzenda type optical coupler and realizes a combined demultiplexing of 1.3 μm and 1.55 μm light. The photoelectric conversion elements are mounted on different substrates, and the optical waveguide and the photoelectric conversion element are optically connected by positioning and fixing the optical waveguide substrate and the substrate on which the photoelectric conversion element is mounted in a ceramic package. The optical fiber has an optical fiber structure with a ferrule having a ferrule attached to one end of the wire, and the wire portion is attached to an optical waveguide substrate with a fiber holder, and the ferrule is held and fixed by a block. The ferrule holding portion by the block enables attachment / detachment to / from the second optical fiber. Further, in order to prevent corrosion of the photoelectric conversion element and dew condensation on the optical coupling portion due to moisture, oxygen, etc., the ceramic package is covered with a lid and adhesively fixed to realize airtight sealing of the optical coupling portion. By reflow soldering the flat leads extending from the ceramic package, it is possible to mount them on a printed wiring board.
