Abstract

In this paper, we report on the design and fabrication of a wavelength demultiplexer integrated with photodetector array in InGaAs/AlGaAs/GaAs structure. The demultiplexer is based on the Rowland circle grating. InGaAs MSM detectors grown on the top of an GaAs/AlGaAs waveguide structure are used for light detection. Only one step epitaxial growth is used. The cross-talk between adjacent channels measured from the detectors response is about -11 dB. The device can provide 38 output channels operating in the 1-μm wavelength region. The structure has the potential to be integrated with GaAs transistors without any complication in the fabrication.
