We employ ultranarrow silicon-on-insulator (SOI) waveguides to demonstrate significant Raman gain using low CW pump powers from a diode laser. Starting with measurements based on spontaneous Raman scattering in nanowire SOI waveguides, we obtain the parameters necessary to develop a useful numerical modeling tool for our system. This work shows clearly the feasibility of an SOI-based low-loss, low-power, on-chip Raman amplifier in the silicon nanowire system. We have also developed a rigorous coupled wave model to examine temporal effects in our Raman system.
