The fabrication of a flat and high responsivity coarse wavelength-division multiplexing (CWDM) photoreceiver using silica-based arrayed-waveguide grating (AWG) with multiple output waveguides was discussed. The device was fabricated using passive alignment technique. The receiver was found to operate at high speed in the CWDM grid, covering the entire S, C and L band range. The results demonstrated that the photoreceiver is promising for use as a multi-channel CWDM photoreceiver in metropolitan networks.
