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…

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…
