Microphotonic RF Receiver Components

High-fidelity quantum transduction with long coherence time superconducting resonators

“…Non-centrosymmetric crystals are used to create interactions between microwave and optical fields using photonic RF three-wave-mixing processes. An electric field applied on the material modulates the refractive index and the incident optical field linearly with the RF voltage (χ (2) ), known as the Pockels effect [2]. We design a 3D hybrid system for quantum transduction through the integration of bulk Nb SRF cavities with optical resonators made of Lithium Niobate (LN: LiNbO 3 ), which is among the best electro-optic materials, with a large electro-optic coefficient (r 33 = 31 pm/V at 9 GHz) and low optical loss.…”
