This paper describes an optical demultiplexer whose diffracted light beams are directly detected by a monolithic linear array of six silicon pin photo-diodes for the 0.8 µm wavelength region. The demultiplexer has 6 channels whose wavelength spacing is 23 nm. Insertion losses and crosstalks were less than 2.1 dB and -25 dB, respectively.
