Hybrid integrated narrow linewidth semiconductor laser based on the distributed feedback from an external deformed microcavity
Da Wei, Leilei Shi, Yujia Li +8
Optical microcavities with rotational symmetry have been widely used for narrowing linewidth and reducing frequency noise, however, the narrow but wavelength dependent optical feed…
Broadband tunable narrow-linewidth laser based on scattering-enhanced fiber covering E-S-C-L bands
Minzhi Xu, Zechun Geng, Da Wei +9
This work demonstrates a broadband tunable narrow-linewidth laser based on scattering-enhanced fiber, covering the E-S-C-L wavelength bands from 1337.47 nm to 1631.39 nm, with a to…
Hybrid integrated narrow linewidth laser with external distributed optical feedback from a silicon strip waveguide
Da Wei, Leilei Shi, Yujia Li +8
External optical feedback via Rayleigh scattering from an integrated microresonator or an optical fiber has been demonstrated to significantly narrow the intrinsic linewidth of sem…
Pump-locked microcavity Brillouin laser
Yuqin Mao, Chaoze Zhang, Ligang Huang +6
Microcavity-based microlasers are the kernel light sources for integrating photonics and optoelectronics. The traditional pump light frequency locking mainly utilizes a complex sys…
