Analysis of Raman lasing in integrated small-volume silicon-on-insulator racetrack resonators

We present a detailed simulation-based analysis of Raman lasing in small- volume silicon-on-insulator racetrack resonators. Continuous-wave Raman lasing in submicron-sized resonant waveguide devices can be expected without the need of additional electronic structures, with a significant improvement in threshold power, device footprint and laser efficiency compared to state of the art integrated Raman lasers on silicon.
