1. An injection locked oscillator comprising:

  • an intensity modulated optical signal delivery system;

    oscillator circuitry; and

    a resonant tunnel diode incorporated in the oscillator circuitry, the resonant tunnel diode being exposed to an intensity modulated optical signal delivered by the optical signal delivery system;

    whereby the resonant tunnel diode is biased such that it oscillates at a free running frequency and the free running oscillation of the resonant tunnel diode is capable of being locked to the phase and frequency of the intensity modulated optical signal when the modulated optical signal approaches the free running oscillation frequency.
