摘要：
In this paper, we investigate the enhancement of Raman amplification bandwidth with self phase modulation (SPM) effect in silicon based photonic crystal waveguides. The Maxwell equations are solved using finite difference time domain method considering two photon absorption, free carrier absorption, Kerr and SPM effects. We also study the effects of shape, width and average power on the Raman amplification bandwidth. Then by changing the photonic crystal geometrical parameters, pump and signal group velocity are reduced to achieve higher Raman bandwidth.
