Abstract
본 발명은 광통신용 반도체 레이저 제조방법에 관한 것으로, 종래에는 통신용에 쓰이는 파장 1.3㎛의 빛을 나타내는 반도체 레이저의 경우 DFB-LD를 만들기 위한 그레이팅의 주기가 대략 196nm로서 매우 작은 것이기 때문에 레이저 간섭장치를 사용해야만 그러한 주기의 그레이팅패턴을 제작할 수 있다. 따라서, 디스트리뷰트 피드백 레이저 다이오드(DFB-LD)를 이용해서 단일모드의 레이저를 제작하는 것은 기술적으로 상당한 어려움이 있고, 고가의 레이저 간섭장치를 사용해야하는 단점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a semiconductor laser for optical communication, and in the case of a semiconductor laser that exhibits light having a wavelength of 1.3 占 퐉 used for communication, the laser interference device is very small because the grating cycle for making DFB-LD is about 196 nm. It can only be used to produce grating patterns of such a cycle. Therefore, fabrication of a single mode laser using a distributed feedback laser diode (DFB-LD) has a considerable technical difficulty and a disadvantage of using an expensive laser interference device.
본 발명은 이러한 문제점을 해결하기 위하여 그레이팅패턴을 사용하지 않고서도 완전한 단일모드의 레이저 빛을 얻을 수 있도록 하고, 기술적으로 보다 훨씬 쉽게 단일모드로 발진하는 반도체 레이저를 제작할 수 있도록 하는 광통신용 반도체 레이저 제조방법을 제공하는 것이다.In order to solve this problem, the present invention enables to obtain a full single mode laser light without using a grating pattern, and to manufacture a semiconductor laser for optical communication, which makes it possible to manufacture a semiconductor laser oscillating in a single mode much more technically. To provide a way.
