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…
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…
Intrinsic Spectrum Analysis of Laser Dynamics Based on Fractional Fourier Transform
Ligang Huang, Tianyi Lan, Chaoze Zhang +8
Intrinsic spectrum that results from the coupling of spontaneous emission in a laser cavity, can determine the energy concentration and coherence of lasers, which is crucial for th…
