Microwave-optical photon interface apparatus and method

Abstract

Microwave-optical interface apparatus and methods are disclosed. In one example embodiment, a microwave-optical interface apparatus comprises: a microwave cavity operable to, at least, host at least one microwave signal photon; and an optical cavity comprising a plurality of embedded defects, the optical cavity operable to, at least, host at least one optical signal photon and at least one optical pump electric field, the optical cavity positioned relative to the microwave cavity to cause, using the plurality of embedded defects and induced by the at least one optical pump electric field, three-wave mixing magneto-optic transduction between the at least one microwave signal photon, the at least one optical signal photon and the at least one optical pump electric field within the optical cavity; wherein the at least one optical signal photon and the at least one optical pump electric field are evanescently confined within the optical cavity in at least two dimensions.
