Abstract

A scheme of all-optical QPSK signal regeneration is proposed which based on cross phase modulation (XPM) in semiconductor optical amplifier (SOA) with subsequent an optical filter. Simulations and theoretical analysis are conducted to validate the feasibility of the proposal. The QPSK signal is distorted by the negative chirp after fiber transmission, and then the distorted QPSK will be regenerated due to the positive chirp which is induced by XPM in the SOA. A power penalty 2.3dB is improved after QPSK regeneration with the receiver sensitivity of -30.7dBm.
