1. A monolithic photonic resonator comprising:
a bulk optic with (i) one or more additional facets off of which light inside the bulk optic undergoes total internal reflection, (ii) a first and a second superpolished facet; and
a high-reflectivity coating applied to each of the first and the second superpolished facets;
wherein the first and second superpolished facets (i) form an optical resonator and (ii) cooperate with the one or more additional facets to define a mode structure of the optical resonator.
