摘要
All-optical switching based on cross-phase modulation using Bragg grating in the highly nonlinear photonic crystal fiber (PCF) is investigated numerically. Differential method is used in the simulation process. The numerical solutions of the coupled-mode equations which describe all-optical switching are presented. Switching characteristics influenced by different pump shape and pump power are analyzed. Furthermore, switching characters of using Bragg grating in a highly nonlinear photonic crystal fiber and in a conventional one are compared.
