Abstract

Opto- and electromechanical systems have separately shown great progress in reaching ultrasensitive displacement readout and manipulation of nano- and micromechanical resonators at the quantum level [1,2,3]. Besides that, combining optical and electrical degrees of freedom via a mechanical interface is of potential interest, as it would allow for low noise optical detection and laser cooling of weak electrical excitations. In a recent paper [4], a scheme was proposed for room temperature applications where a membrane converts rf electrical excitations in an LC circuit to optical excitations in a high finesse cavity.
