High-efficiency Brillouin lasing in a planar GeSbS spiral-ring resonator

扫码查看
Stimulated Brillouin scattering in planar integrated circuits promises to realize compact and highly coherent lasers.Here we report efficient Brillouin lasing at telecommunication wavelength from a planar Ge25Sb10S65 chalcogenide[ChG]resonator with a high quality factor above 106.A low lasing threshold of 24.8 mW is achieved with a slope efficiency of 8.3%.An 8-kHz linewidth is measured for 1.56-mW on-chip output power.This work offers a good opportunity to enrich the versatility and functionality of the ChG photonics on account of their intrinsic advantages of low loss,high third-order nonlinearity,and potential capacity for wafer-scale fabrication.
