  • Optical wavelength demultiplexing filter for passing a selected one of a plurality of optical wavelengths
    Patent number: 5408319
    Abstract: A method and apparatus for selecting an optical wavelength is provided incorporating a layer of silicon with two juxtaposed partially-reflective mirrors to provide a Fabry-Perot cavity and ohmic contacts to the silicon layer for heating the silicon layer to provide a temperature change to change its index of refraction. The invention overcomes the problem of mechanically tuning a Fabry-Perot cavity for wavelength division multiplexing (WDM).
