1. An optical resonator system comprising:

  • an optical resonator, made substantially entirely from CaF2, shaped to support at least one whispering gallery mode and comprising a top surface, a bottom surface, a side wall, and a first curved transition region extending between the side wall and the top surface; and

    a coupler including a coupling surface, wherein the coupling surface defines a first plane and the optical resonator top surface defines a second plane wherein the first plane and second plane intersect at an acute angle;

    wherein the coupling surface of the coupler is arranged to face the transition region of the optical resonator and in the vicinity thereof such that an evanescent field emitted from the coupler is capable of being coupled into the optical resonator through the first curved transition region.
