Abstract
Small signal frequency response of a silicon nanocrystal based slotted photonic crystal Raman laser has been evaluated theoretically by solving the coupled mode equations for laser in steady state. Modulation bandwidth of the order of ~ 144 GHz has been achieved in this type of laser due to the high Raman gain coefficient of silicon nanocrystal.
