초록

상온에서 단일소자의 경우 $0.98{\mu}A$ 문턱전류를 나타내는 $32{\times}32$ 광양자테 레이저 어레이를 제작하였다. 제작된 어레이의 전체 소자들의 문턱전류 및 밀도, 전압은 20 mA, $0.068A/cm^2$, 1.38 V의 값을 나타내었다. 발광 광양자테 어레이는 GaAs 물질이 다중-양자 우물 활성 영역을 구성하고, 칩이 차지하는 면적은 $1.65{\times}1.65mm^2$였으며, 소자들의 피크파워 파장은 $858.8{\pm}0.35nm$, 상대적인 레이저 세기는 $0.3{\pm}0.2$, 선폭은 $0.2{\pm}0.07nm$로 비교적 균일한 특성을 보였다. 또한, 레이저 어레이의 각도 의존적 청색 이동 특성을 이용한 파장 분할 멀티플렉싱 시스템 실험을 진행하였고, 각도에 따라 10 nm 정도 파장이 변하는 현상을 발견하였으며, 거리에 따른 레이저 세기를 측정한 결과 6 m에서도 감지할 수 있음을 확인하였다.
