In quantum optical devices, microcavities can coax atoms or quantum dots to emit spontaneous photons in a desired direction or can provide an environment where dissipative mechanisms such as spontaneous emission are overcome so that quantum entanglement of radiation and matter is possible.
A picogram- and nanometre-scale photonic-crystal optomechanical cavity
Measurements of an optical system consisting of a pair of specially patterned nanoscale beams in which optical and mechanical energies are simultaneously localized to a cubic-micron-scale volume and for which large per-photon optical gradient forces are realized enable the exploration of cavity optomechanical regimes.

It is demonstrated here experimentally and theoretically self-stable equilibrium solution for a pump-microcavity system; this mechanism is derived by the thermal nonlinearity.
Label-Free, Single-Molecule Detection with Optical Microcavities
A highly specific and sensitive optical sensor based on an ultrahigh quality (Q) factor (Q > 108) whispering-gallery microcavity is reported and label-free, single-molecule detection of interleukin-2 was demonstrated in serum.
These planar optomechanical crystals bring the powerful techniques of optics and photonic crystals to bear on phononic crystals, providing exquisitely sensitive (near quantum-limited), optical measurements of mechanical vibrations, while simultaneously providing strong nonlinear interactions for optics in a large and technologically relevant range of frequencies.
Chemically etched ultrahigh-Q wedge-resonator on a silicon chip
Ultrahigh-Q optical resonators are being studied across a wide range of fields, including quantum information, nonlinear optics, cavity optomechanics and telecommunications. Here, we demonstrate a…
