Micro- and nano-optomechanical systems

Ongoing
Our primary current research direction involves the use of fabricated devices with sub-wavelength periodicity (photonic crystals) as optomechanical elements. Such structures enable a rich variety of devices, including mirrors, polarizers, and filters, in a configuration that couples naturally to

Measuring Light-Matter Interactions in Chip-Based Optical Cavities

Ongoing
A "single emitter" is a structure that exhibits a transition from a high energy state to a low energy state, thereby generating a photon, or light emission. A variety of solid-state single emitters have been discovered or manufactured. One example is a quantum dot, a nanometer-scale structure that

Nonlinear nanophotonic control of light

Ongoing
Light-matter interactions with nonlinear materials provide a powerful tool for converting optical fields from one state to another. For example, nonlinear wavelength conversion leverages efficient scattering of photons of a single frequency to another, enabling generation of coherent sources across
