The combination of the large per-photon optical force and small motional mass achievable in nanocavity optomechanical systems results in strong dynamical back-action between mechanical motion and the cavity light field. In this Article, we study the optical control of mechanical motion within two different nanocavity structures, a zipper nanobeam photonic crystal cavity and a double-microdisk whispering-gallery resonator. The strong optical gradient force within these cavities is shown to introduce significant optical rigidity into the structure, with the dressed mechanical states renormalized into optically bright and optically dark modes of motion. With the addition of internal mechanical coupling between mechanical modes, a form of optically controlled mechanical transparency is demonstrated in analogy to electromagnetically induced transparency of three-level atomic media. Based upon these measurements, a proposal for coherently transferring radio-frequency/microwave signals between the optical field and a long-lived dark mechanical state is described.

Colloquium: Strongly interacting photons in one-dimensional continuum (2016, background): “An entirely different approach that has shown promise is to use optomechanical systems, where mechanical vibrations (phonons) in nano- or micro-mechanical systems act as an intermediary between the microwave and optical photons (Andrews et al., 2014; Bochmann et al., 2013; Lin et al., 2010).”
Giant enhancement of stimulated Brillouin scattering in the sub-wavelength limit (2012, methodology): “In particular, using simultaneous optical and phononic resonances, radiation-pressure-mediated photon-phonon couplings have enabled cryogenic optomechanical cooling [25,35], phonon lasers [36], and phononic signal processing [37–39].”
