Widely tunable silicon Raman laser

Authors: Ahmadi, MohammadShi, WeiLaRochelle, Sophie
Abstract: Stimulated Raman scattering is an effective means of wavelength conversion and can largely extend the operating spectral range of an optical source. We demonstrate a highperformance tunable Raman laser on a sub-micrometer-thick silicon on insulator wafer using a standard foundry process. The key feature to this laser is the use of a tunable coupling mechanism to adjust both pump and signal coupling coefficients in the ring cavity, allowing demonstration of laser emission over a large wavelength tuning range of 83 nm. This Raman laser demonstrates efficient (slope of up to 26% and a maximum pump-to-signal power conversion efficiency of 10%) on-chip non-linear wavelength conversion. Our results indicate great promise for substantially increasing the optical spectral resources available on a silicon chip.
