The study of mechanical resonators coupled to optical cavities has emerged as a new frontier in quantum optics. By utilizing low-optical-loss and high-Q micromechanical elements, researchers can now harness radiation pressure to deeply cool mesoscopic mechanical motion. I will discuss my group’s recent work on (1) cooling a silicon nitride membrane towards its quantum mechanical ground state in a monolithic Fabry-Perot cavity and (2) understanding the mechanical damping of highly-tensioned membranes made from different materials. Our goal is to create an optomechanical platform for hybrid electro-optomechanical devices that are the focus of a collaborative effort between my group and Konrad Lehnert’s group at JILA. These proposed devices hold potential for creating a microwave to optical quantum link.
