Analysis of the Characteristics of All-optical Switch Based on the SPM and XPM
|
Abstract:
A new method for the optimization of all-optical EDFA-based Sagnac interferometer switch is presented.The effects of the small signal gain and the saturation output power of EDFA on the performance of the switch are investigated using an analytical model for all-optical switch based on self-phase or cross-phase modulation.There exists a critical value of the high nonlinear photonic crystal fiber(HNPCF)length for switching due to the limitation of the EDFA.When the HNPCF length required for switching is fixe...
