Abstract

A scheme of optical 16-QAM signal generation based on XPM in nest semiconductor optical amplifier based Mach-Zehnder interferometer (SOA-MZI) is proposed. In this proposal, 10Gbit/s QPSK and 16-QAM signal can be generated. Simulations and theoretical analysis have been conducted to validate the feasibility of the proposal by VPItransmissionMaker 8.5. A power penalty below 1.75dB is obtained after the transmission over 160km along single mode fiber with a receiver sensitivity of -28.5dBm.
