1. A splitterless optical broadcast switch for routing a plurality of optical carrier signals, said splitterless optical broadcast switch comprising:

  • an optical source operable to generate a plurality of unmodulated optical carrier signals;

    a first stage routing module optically coupled to said optical source, said first stage routing module operable to route said plurality of unmodulated optical carrier signals;

    a modulating module optically coupled to said first stage routing module, said modulating module operable to receive a plurality of RF input signals and operable to modulate each of said RF input signals received onto any number of said unmodulated optical carrier signals to generate a plurality of modulated optical carrier signals;

    a second stage routing module optically coupled to said modulating module, said second stage routing module operable to route said plurality of modulated optical carrier signals complimentary to said first stage routing module; and

    an output module operable to receive said plurality of modulated optical carrier signals, wherein each optical output from said optical source is paired to a complimentary optical input of said output module.
