Abstract

We demonstrate the integration of a grating demultiplexer with curved output waveguides and MSM photodetector array in In GaAs/AlGaAs/GaAs operating in the 1 µm wavelength region. The structure provides 38 channels with 1 nm channel spacing. The total loss including scattering from unmetalized grating is about 17 dB. A channel crosstalk of -11 dB is obtained. The FWHM of the channel pass band is 0.5 nm.
