SEM Micrograph of a Microtoroidal Resonator

Caption

SEM micrograph of a microtoroidal resonator similar to the one used for demonstration of quantum-enhanced feedback cooling. The silica torus forms a cavity for light which is modulated by the mechanical vibrations of the supporting disk. Light is coupled in and out of the system by bringing a tapered optical fiber in proximity of the torus.
