1. A opto-electronic device, comprising:

  • a substrate formed of a semiconductor;

    a semiconductor laser formed on said substrate to produce a laser beam;

    a semiconductor optical modulator formed on said substrate to receive and modulate said laser beam from said semiconductor in response to an electrical modulation signal;

    a first waveguide formed on said substrate and coupled to receive a modulated optical signal from said optical modulator;

    an optical resonator formed on said substrate and coupled to said first waveguide to receive a portion of said modulated optical signal;

    a second waveguide formed on said substrate and coupled to receive a portion of said modulated optical signal in said optical resonator;

    a semiconductor photodetector formed on said substrate to receive and convert an optical output from said second waveguide into an electrical signal; and

    an electrical link formed on said substrate and coupled between said photodetector and said optical modulator to produce said electrical modulation signal from said electrical signal.
