1. An opto-electronic device, comprising:

  • a laser, having an internal active optical feedback loop with a first loop gain greater than unity and responsive to an electrical modulation signal, said laser operating to produce a coherent optical oscillation; and

    an opto-electronic feedback loop with a second loop gain greater than unity, receiving an optical signal indicative of said optical oscillation and converting said optical signal into said electrical modulation signal having a relation with said optical oscillation, said electrical modulation signal affecting said optical loop and said optical oscillation.
