Optical microcavities

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.

Phonon laser action in a tunable, two-level system

A compound optical microcavity system, coupled to a radio-frequency mechanical mode, operating in close analogy to a two-level laser, causing phonon laser action above a pump threshold of 7 µW is demonstrated.

Dynamical thermal behavior and thermal self-stability of microcavities

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.

Optomechanical crystals

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.
