Abstract

In this paper, we propose a new tunable laser diode structure. The laser diode consists of a sampled-grating distributed feedback laser diode monolithically integrated with a sampled-grating distributed-Brags-Reflector. For a specific design, the possibility of continuous/discrete wavelength tuning over 27nm is confirmed by a numerical analysis using a split-step time domain model. Because the laser diode can be directly coupled with optical fiber without the intervention of the passive section, the laser diode exhibits higher output power than the conventional laser diode.

본 논문에서는 새로운 구조의 파장가변 레이저 다이오드를 제안하였다. 제안된 레이저 다이오드는 추출격자 분포궤환 레이저 다이오드와 추출격자 분포 브래그 반사기가 집적된 구조로 되어 있다. 제안된 레이저 다이오드는 특정한 구조에서 27 nm정도의 광대역 파장가변이 가능함을 수치해석을 통해 확인하였다. 또한 이득영역에서 생성된 광파를 다른 수동영역을 거치지 않고 직접 광섬유에 결합시킬 수 있는 구조로 광효율이 기존의 레이저 다이오드에 비해 우수함을 확인하였다.
