Compact narrow-linewidth heterogeneously integrated laser based on self-injection-locking to a high-Q WGM microresonator module
We implement sub-Hz-level instantaneous linewidth (70dB linewidth compression) laser source by self-injection locking to a high-quality-factor (⪆10e8) WGM microresonator module with locking time of more than 24 hours. We independently developed a few mode, high-quality-factor micro-cavity module which directly integrated with DFB chip. The entire optical module can be packaged to enhance robustness, making it truly commercialized and compatible to industrial optical systems.
