Abstract

We propose a novel and simple non-return-to-zero differential phase shift keying (NRZ-DPSK) wavelength division multiplexing (WDM) system which can simultaneously demultiplex and demodulate multiple wavelengths. The phaseto- intensity demodulation principle is based on detuned filtering, which is achieved by using a single commercial array waveguide grating (AWG) in our scheme. By properly choosing appropriate AWG channels at the transmitter, the AWG at the receiver can act as both the de-multiplexer and the demodulator of the DPSK signals. Simulations at 10, 20 and 40Gb/s show good flexibility and performance for the proposed system.
