Interference effects in cavity optomechanics with hybridized membranes
Abstract
Radiation pressure forces in cavity optomechanics allow for efficient cooling of motion, the manipulation of photonic and phononic quantum states, as well as generation of optomechanical entanglement. The standard mechanism relies on the cavity photons directly modifying the mechanical state. Hybrid cavity optomechanics provides an alternative approach by coupling mechanical objects to quantum emitters, either directly or indirectly via the common interaction with a cavity field mode. In these systems, the interference between forces from the cavity field and the emitters can give rise to novel optomechanical phenomena. We analyze two such hybrid optomechanical systems where a vibrating membrane is doped by quantum emitters or patterned with a photonic crystal structure. In particular, we demonstrate that, in the former system, a three-body interaction between the cavity field, emitters, and mechanical motion can be used to improve cooling of the mechanical motion. Second, we show that, when an esnemble of emitters or a photonic crystal structure in the membrane strongly modifies the membrane reflectivity, the cavity linewidth can be significantly reduced and the system can reach the sideband resolved regime.
