활성층 구조에 따른 DFB-LD의 선폭확대계수 및 미분이득 비교
Comparison of linewidth enhancement factor and differential gain of DFB-LDs with various active layter structures
초록
Linwidth enhancement factor .alpha., linwidth, chirping and differential gain characteristics were measured and compared for each DFB-LDs containing active layers composed of bulk, MQW, and S-MQW, respectively. .alpha. of 6, 4 and 3.2 and chirping measured under 2.5Gbps modulation of 1.29nm, 0.67nm and 0.48nm were given for DFB-LDs of bulk, MQW and S-MQW active layers, respectively. And S-MQW has the largest differential gin of 2.4*10
