Coupling RF-driven acoustic wave devices with nanocavity optomechanics — •Kartik Srinivasan, Marcelo Wu, Marcelo Davanco, and Krishna Balram — National Institute of Standards and Technology, Gaithersburg, MD 20899, USA

Nanocavity optomechanical systems are being developed for a variety of sensing and signal transduction applications. Optomechanical crystal cavities, which co-localize optical modes within a photonic bandgap and mechanical modes within a phononic bandgap, have been of particular interest due to the strong interactions they support. Here, I will describe our efforts in connecting such devices to radio frequency (RF) waves, through the development of a piezoelectric cavity optomechanics platform. Frequency and time-domain characterization of devices within this platform will be presented, as will efforts to improve the overall efficiency of microwave-to-optical transduction.
