Waveguide Bragg-grating based all-optical wavelength-routing switch with wavelength conversion
An all-optical switch with wavelength conversion is disclosed. The optical switch comprises an input waveguide for carrying a multiplexed optical signal comprised of a plurality of wavelength channels. Further included is a demultiplexer for separating the multiplexed optical signal into the plurality of wavelength channels. The wavelength channels are then provided to a wavelength converter operative to convert the wavelength channels into a converted wavelength channel. The converted wavelength channels are input to a switch operative to switch the converted wavelength channels onto output waveguides.
