1. A laser stabilization system comprising:

  • a laser source having a first end and a second end;

    a first waveguide portion having a first end and a second end, the first end of the first waveguide portion coupled to the first end of the laser source;

    a second waveguide portion having a first end and a second end, the first end of the second waveguide portion coupled to the second end of the laser source;

    a micro-cavity coupled between the second end of the first waveguide portion and the second end of the second waveguide portion, the micro-cavity having a resonant frequency;

    an electronic locking loop coupled between the micro-cavity and the laser source, wherein the electronic locking loop electronically locks the laser source to the resonant frequency of the micro-cavity;

    wherein the first waveguide portion is an optical locking loop coupled between the micro-cavity and the laser source, wherein the optical locking loop optically locks the laser source to the resonant frequency of the micro-cavity;

    a micro-cavity stabilization loop coupled with the micro-cavity, wherein the micro-cavity stabilization loop stabilizes the resonant frequency of the micro-cavity to a reference frequency; and

    an output for outputting light from the laser stabilization system.
