View Presentation Abstract
Uwe von Lüpke
We present our advances in developing a cryogenic cavity optomechanical device based on a bulk-acoustic-wave (BAW) mechanical resonator, which can act as an essential part of a MW-to-optical transducer. Strong coupling to BAWs has been demonstrated both for microwave photons  and for optical photons . Building on these works, we are developing an optomechanical system that is also compatible with coupling to superconducting circuits. We report on first experiments of BAW resonators cooled to millikelvin temperatures and coupled to optical cavity modes. As a first proof-of-principle, we discuss prospects for storage and retrieval of low-photon-number coherent optical states in the mechanical resonator.
