1. An optical resonator comprising:

  • a plurality of segments of an optical waveguide, the optical waveguide being a slab optical waveguide on a substrate;

    a plurality of total internal reflection (TIR) mirrors, a number of TIR mirrors in the plurality of TIR mirrors being equal to a number of segments in the plurality of segments; and

    a photo-tunneling input/output (I/O) port,wherein the plurality of segments of the optical waveguide is arranged as a closed loop wherein successive pairs of the segments are connected to one another at respective segment ends by successive ones of the TIR mirrors, andwherein the photo-tunneling I/O port comprises a designated TIR mirror of the successive TIR mirrors of the plurality of TIR mirrors.
