1. An optical device comprising a waveguide network, a sideband generator, and an optical filter, wherein:

  • said waveguide network is configured to direct an optical signal from an optical input of said optical device through said sideband generator and said optical filter to an optical output of said optical device;

    said sideband generator comprises an electrooptic interferometer comprising first and second waveguide arms and a modulation controller configured to drive said sideband generator at a control voltage substantially larger than Vπ

    to generate frequency sidebands about a carrier frequency of said optical signal, where Vπ

    represents the voltage at which a π

    phase shift is induced between respective arms of said interferometer; and

    said optical filter is configured to discriminate between said frequency sidebands and said carrier frequency such that sidebands of interest can be directed to said optical output.
