  • Abstract
    An echelette grating is fabricated on a silicon surface by anisotropic etching. A five channel demultiplexer using this grating for a wavelength-division-multiplexing system is developed in the 0.8-μm wavelength region. The wavelength spacings are 250 Å. This system´s insertion loss for five channels is 1.4, 1.1, 1.1, 1.1, and 1.2 dB, respectively, and crosstalk levels are <-30 dB.
