The Photonic Systems Laboratory currently supports multiple research thrusts in signal processing, sensing, and communications. The group has developed a new class of parametric devices and used them to achieve records in terabit-scale signal processing, analog-to-digital signal conversion, and high-quality wide-band frequency combs. The core capability of the laboratory, nanometer-scale mixer synthesis, is enabled by a unique facility developed over a half-decade period. The new technology is currently used to construct new classes of agile oscillators and signal processors capable of establishing new records in signal speed, fidelity, and dissipation.

 

In the second thrust, the laboratory hosts research on communication and sensing in bandwidth constrained physical channels. This technology has led to record spectral efficiencies in optical and free-space links and is currently being developed in both optical and RF domains.
