초록
850 nm 대역의 발진 파장을 갖는 GaAs/AlGaAs 다중양자우물 레이저 다이오드의 lateral-mode 특성과 이 특성이 출력 광파워 kink 에 미치는 영향을 조사하였다. 이를 위해 전기적-열적-광학적 시뮬레이션을 self-consistent하게 수행하고, 제작된 레이저 다이오드 소자들을 측정하였다. 연구 결과를 바탕으로 높은 출력 파워에서도 single lateral-mode를 유지해서 좋은 beam quality를 유지할 수 있는 최적의 P-cladding 두께를 결정하였다.
Abstract
The lateral-mode characteristics of 850-nm GaAs/(Al,Ga)As multiple-quantum-well laser diodes and their influence on the kinks in output opticalpower are investigated. For the investigation, self-consistent electro-thermal-optical simulation and measurement of fabricated devices are used. From this investigation, the optimal P-cladding thickness that provides single-lateral-mode operation is determined, so that high beam quality can be achieved even at high output powers.
