A Novel Architecture for room temperature microwave optomechanical experiments

Abstract

We have developed a novel architecture for room temperature microwave cavity optomechanics, which is based on the coupling of a 3D microwave reentrant cavity to a compliant membrane. Devices parameters have enabled resolving the thermomechanical motion of the membrane, and observing optomechanically induced transparency/absorption in the linear regime, for the first time in a microwave optomechanical system operated at room temperature. We have extracted the single photon coupling rate (g0) using four independent measurement techniques, and hence obtain a full characterization of the proposed cavity optomechanical system.
