Raman Gain in Silicon Using Highly Confined Waveguide Structure
We show ultra-fast Raman gain dynamics in submicron-size silicon-on-insulator strip waveguide. Using high confinement structures and pico-second pump pulses, we show 6-dB net nonlinear gain with 20.7-W peak pu...

Light Guiding in Low Index Materials using High-Index-Contrast Waveguides
We propose a novel high-index-contrast waveguide structure capable of light strong confinement and guiding in low-refractive-index materials. The principle of operation of this structure relies on the electric...
