Abstract:
1. An electrooptic source comprising an optical signal generator, optical circuitry, and at least one optical/electrical convener wherein the structure of the source is such that at least the following conditions apply: the optical signal generator comprises a sideband generator and an arrayed waveguide grating (AWG) comprising multiple frequency channels characterized by optical outputs having distinct output frequencies; the optical circuitry comprises a switching circuit configured to permit selection and combination of different ones of the distinct-frequency optical outputs of the optical signal generator to generate a modulated optical signal characterized by a modulation frequency of at least about 30 GHz; the optical circuitry further comprises a data encoder configured to encode data onto the modulated optical signal; the optical circuitry is further configured to direct the modulated, encoded optical signal to at least one optical/electrical converter; and the optical/electrical converter is configured to convert the modulated, encoded optical signal to a millimeter or sub-millimeter wave.
