Abstract
We report the experimental demonstration of optomechanical light storage in a
silica resonator. We use writing and readout laser pulses tuned to one
mechanical frequency below an optical cavity resonance to control the coupling
between the mechanical displacement and the optical field at the cavity
resonance. The writing pulse maps a signal pulse at the cavity resonance to a
mechanical excitation. The readout pulse later converts the mechanical
excitation back to an optical pulse. The light storage lifetime is determined
by the relatively long damping time of the mechanical excitation.
