A novel architecture for room temperature microwave optomechanical experiments

We have developed a novel architecture for room temperature microwave cavity optomechanics, which is based on the coupling of a 3D microwave re-entrant cavity to a compliant membrane. Device 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 ( g 0) using four independent measurement techniques and, hence, obtained a full characterization of the proposed cavity optomechanical system.

We have developed a novel architecture for microwave cavity optomechanics at room temperature, using a 3D microwave re-entrant cavity and a compliant membrane. By resolving the thermomechanical motion of the membrane, we observed optomechanically induced transparency/absorption for the first time in a microwave optomechanical system operated at room temperature. Single-photon coupling rate (g0) was extracted through four independent measurement techniques, providing a full characterization of the proposed cavity optomechanical system.
