Integrated Quantum Photonics

We are interested in the device-level development and system-level application of integrated photonics technologies for quantum communications, computing, sensing, and metrology. Devices under current development including single-photon and entangled-photon pair sources and quantum frequency converters.

Nonlinear Nanophotonics

We are developing nonlinear nanophotonic technologies to realize classical and quantum photonic links across widely separated regions of the optical spectrum. This includes optical frequency combs to enable portable optical atomic clocks, new compact laser sources that can flexibly reach a broad range of output frequencies, and efficient and low-noise frequency converters suitable for quantum states of light.

Nanoscale electro-optomechanical transducers

We develop integrated cavity opto/electromechanical systems for sensing and signal transduction applications. Current efforts include microwave-to-optical quantum transducers using piezoelectric optomechanical systems, the integration of NEMS to enable feedback stabilization and tuning of optomechanical devices, and the application of cavity optomechanics for thermometry.

Photonic integrated circuits with atomic vapors

Alkali atomic vapors provide a unique resource for nonlinear and quantum optics, including a strong resonant nonlinearity, relative homogeneity in comparison to most solid-state systems, and relatively limited physical infrastructure requirements for operation.  We are developing chip-scale platforms that combine photonic integrated circuits with atomic vapors. 

Integrated photonics design, fabrication, and characterization tools

Integrated photonics provides access to a wide range of geometries and materials systems in which light-matter interactions can be harnessed to realize physically useful functions for applications in areas such as quantum information science, metrology, and sensing.
