Abstract: PURPOSE: An optical transmission module using a silicon optical bench is provided to reduce a distance between a light source and a photo detector and to control light intensity incident on the light source and the photo detector easily, thereby reducing light loss and preventing an unstable operation of the light source. CONSTITUTION: A silicon optical bench(SiOB)(11) has a slant side wall(12) and has an open concave part(13) on its another side, and an optical fiber alignment part(15) is formed on the open side of the concave part, and a groove(16) is formed between the slant side wall and the optical fiber alignment part. An optical fiber(14) is mounted on the optical fiber alignment part, and a light source(17) is installed on an upper part of the slant side wall. And a photo detector(18) is installed on an upper part of the groove. A light emitted from the light source is reflected from the slant side wall and then is transferred to the optical fiber, and a part of the light is reflected from the side wall of the groove and is incident on the photo detector.

Abstract: 본 발명은 실리콘 광벤치를 이용한 광송신 모듈에 관한 것으로, 광원으로부터 방출된 광의 경로를 광섬유 방향으로 변환시키기 위한 실리콘 광벤치의 반사면에 홈을 형성하고 홈에서 반사된 일부의 광이 광검출기로 입사되도록 하므로써 광원과 광검출기 간의 거리를 감소시킬 수 있어 소형화가 용이해지며 광검출기까지의 광의 경로가 최소화되어 정확한 모니터링이 이루어진다. 또한, 방출된 광의 대부분이 광섬유 방향으로 진행됨에 따라 광섬유와 능동소자 간의 광결합 효율이 향상된다.
