Abstract
We demonstrate the integration of a grating demultiplexer with curved output waveguides and MSM photodetector array in InGaAs/AlGaAs/GaAs op erating in the 1 mum wavelength region. The structure provides 38 chan nels with 1 nm channel spacing. The total loss including scattering fr om unmetalized grating is about 17 dB. A channel crosstalk of -11 dB i s obtained. The FWHM of the channel pass band is 0.5 nm.
