Near-field cavity optomechanical probing of nanomechanics

An optical fiber taper placed in the near field of a "split-beam" photonic crystal nanobeam cavity with a physical gap at the cavity center breaks the system's vertical dielectric symmetry, enabling selective optomechanical coupling to multiple cantilever resonances using a single optical nanocavity mode. \ua9 2013 Optical Society of America.Peer reviewed: YesNRC publication: Ye
