Electro-optic transducer with integrated optical delay line

Abstract

Devices and/or methods provided herein relate to providing conversion of photons between an optical domain and a microwave domain. An electronic structure can comprise a resonator assembly comprising a microwave resonator and an optical resonator, an optical pump waveguide that transmits an optical pump input to the resonator assembly, and an optical signal waveguide, separate from the optical pump waveguide, that transmits an optical signal relative to the resonator assembly. The electronic structure further can comprise a microwave signal waveguide that transmits a microwave signal relative to the resonator assembly. The optical pump waveguide can comprise a delay portion that delays receipt of the optical pump input to the resonator assembly through the optical pump waveguide to a time after reduction of a majority of decoherence of the resonator assembly caused by scattering of a portion of the optical pump input, which portion does not enter the optical pump waveguide.
