Here, we present our on-going efforts on an on-chip REI-based microwave to optical transducer using 171Yb3+: YVO4, with integrated superconducting microwave resonators and gold reflectors. The microwave resonator was fabricated out of niobium on top of 171Yb3+: YVO4 substrate. A thin layer of gold was evaporated on the back of the chip for light collection. We characterized the transducer performance at dilution temperature. Strong coupling between the resonator and excited state spin was observed. We calibrated efficiencies in both continuous-wave mode and pulsed mode. The added noise during pulsed operations was measured on a single photon detector. We’ll discuss the future directions as well in the presentation.
