Cavity Nano-Optomechanics with Suspended Subwavelength-Sized Nanowires

An ongoing line of inquiry in cavity optomechanics consists of increasing the strength of the light-oscillator interaction to explore various dynamical regimes. By combining a high-finesse microcavity with an ultrasensitive force sensor (a suspended SiC nanowire), one can reach the regime where a single photon in the cavity has a measurable impact on the nanoresonator.
The internal optical resonances of the nanowire strongly structure and possibly enhance the light-nanowire interaction, which can be fine-tuned through careful positioning of the subwavelength-sized nanowire within the standing wave inside the cavity.
