Abstract

See full text

Systems and methods for providing a microwave-to-optical (M2O) transducer using magneto-optical field interactions with spin states of an ensemble of ions doped into a crystal structure is presented. According to one aspect, the crystal structure is a (171Yb3+:YVO) doped crystal structure that provides a substrate for an on-chip implementation of the transducer. According to one aspect, coupling of microwave and optical signals to the ions is based on respective microwave and optical waveguides fabricated in or on the doped crystal structure. According to another aspect, coupling of microwave and optical signals to the ions is based on respective microwave and optical resonant cavities fabricated in or on the doped crystal structure. Transduction can be based on either a three-level system with near-zero applied external magnetic field or on a four-level system with zero applied external magnetic field. The transducer can operate reversibly as an optical-to-microwave (O2M) transducer.
