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).
