8-channel optical demultiplexer realized as SiO/sub 2//Si flat-field spectrograph

The operation of a flat-field spectrograph in silica on silicon (SiO/sub 2//Si) for 2-nm channel spacing is demonstrated. Crosstalk attenuations of >20 dB and significantly reduced fiber-to-fiber insertion losses of 5 dB could be obtained.<<ETX>>
