Abstract
본 발명은 레이저 다이오드 모듈에 관한 것으로, 레이저 다이오드에서 방출되는 레이저 빔의 후방 경로상에 접속렌즈 및 그레이팅(Grating)을 장치함으로써, 레이저 다이오드의 페이싣(Facet)면 후방으로 방출되는 레이저 빔을 접속렌즈및 그레이팅(Grating)으로 다시 레이저 다이오드 활성층으로 접속시킴으로써, 레이저 다이오드 전방으로 방출되는 레이저 빔의 노이즈 성분을 그레이팅(Grating)을 통하여 제거하고, 단일모우드의 파장을 얻는 레이저 다이오드 모듈이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser diode module, wherein a connecting lens and a grating are provided on a rear path of a laser beam emitted from a laser diode, thereby connecting a laser beam emitted behind a facet surface of the laser diode. By connecting the lens and the grating back to the laser diode active layer, the noise component of the laser beam emitted in front of the laser diode is removed through the grating to obtain a wavelength of a single mode.
