High power GaSb-based distributed feedback laser with laterally coupled dielectric gratings at 1.95μm
Zhengqing Ding, Juntian Cao, Kun Zhan +7
Traditional Distributed Feedback (DFB) or Distributed Bragg Reflector (DBR) lasers typically utilize buried gratings as frequency-selective optical feedback mechanisms. However, th…
