Enhanced Raman amplification by photonic crystal based waveguide structure

Abstract

In this paper, we investigate the enhancement of Raman amplification bandwidth in silicon based photonic crystal waveguides with self-phase modulation (SPM) effect. The Maxwell equations are solved using finite difference time domain method considering two photon absorption, free carrier absorption, Kerr and SPM effects. We also studied the effects of shape, width and average power on the Raman amplification bandwidth.
