A compact preamplified receiver for wavelength division multiplexed-diffferential phase shift keying (WDM-DPSK) signals based on Gaussian filtering is proposed and simulated, and a first implementation, including an semiconductor optical amplifiers (SOA) and an ad-hoc arrayed waveguide grating (AWG), is demonstrated by monolithical integration in an InP platform. The demodulation of 56-Gb/s channels on the eight 100-GHz-spaced AWG outputs is experimentally reported, and simulation results show the feasibility of multiwavelength operation obtaining simultaneous demultiplexing and demodulation of all the channels. The resilience to chromatic dispersion for the Gaussian filter demodulation is also shown by simulations.
