Abstract

We show high Raman gain in Silicon submicron-size strip waveguide. Using high confinement structures and pico-second pump pulses, we show 13.2-dB peak gain with 14.6-W peak pump power in a 7-mm long waveguide. The effect of free-carrier absorption is observed. We show a pico-second all-optical switch based on the Silicon waveguide, whose transmission is enhanced by the Raman gain.
