ABSTRACT:
A device for converting the frequency of an optical signal to form a frequency comb having a plurality of frequency spaced optical carriers. In one embodiment, a magnetooptic frequency conversion device is disclosed wherein the frequency of the optical signal is shifted by the frequency of an AC signal generating a magnetic field through a crystal. In another embodiment, acoustooptic scattering is used wherein an acoustic wave is provided to a waveguide which receives an optical signal so that the frequency of the optical signal is shifted by the frequency of the acoustic wave. In yet another embodiment, a single sideband modulator is used to shift the frequency of an optical signal.
