Single-mode InAs/GaAs quantum-dot DFB laser with oxidized aperture confined surface grating
Zhengqing Ding, Anyao Zhu, Chaoyuan Yang +4
InAs/GaAs quantum dot (QD) distributed feedback (DFB) lasers are promising candidates for next-generation photonic integrated circuits. We present a design that incorporates an oxi…
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…
Ultra-low threshold continuous-wave quantum dot mini-BIC lasers
Hancheng Zhong, Jiawei Yang, Zhengqing Ding +5
Highly compact lasers with ultra-low threshold and single-mode continuous wave (CW) operation have been a long sought-after component for photonic integrated circuits (PICs). Photo…
High performance distributed feedback quantum dot lasers with laterally coupled dielectric grating
Zhuohui Yang, Zhengqing Ding, Lin Liu +8
The combination of grating-based frequency-selective optical feedback mechanisms, such as distributed feedback (DFB) or distributed Bragg reflector (DBR) structures, with quantum d…
