Abstract

Based on a novel loss analysis, we numerically demonstrate that bi-directional pumping scheme is an effective technique to achieve loss reduction and maximum output power enhancement in silicon Raman laser. We then investigate the influence of cavity end-facet reflectivity under the bi-directional pumping scheme. Low end-facet reflectivity cavity simultaneously maximizes the output power and enhancement effect of bi-directional pumping, resulting in a fully optimized peak Stokes output.
