We perform optimization of all-optical EDFA-based Sagnac – interferometer switch through an analytical model and numerical simulations by solving nonlinear Schrödinger equations. The effects of the performance of EDFA on the bit rate and the switching power are investigated for all-optical switch based on self-phase or cross-phase modulation. The simulated results show that ultra-low switching power (<1mW) all-optical switch for 40 Gb/s data can be realized by properly selecting the length of highly nonlinear photonic crystal fiber and adjusting the performance of EDFA.
