Integrated Photonics for Lidar, RF Signal Processing, and Quantum Sensing

Integrated photonic technologies show great promise for enabling the miniaturization, scaling, and environmental hardening of sensing systems including lidar, microwave receivers, and atom-based sensors and clocks. To support such applications, MIT Lincoln Laboratory has established in-house integrated photonics platforms that operate at wavelengths ranging from the ultraviolet to the near-infrared. We will describe these platforms and their use to realize a novel planar-lens-based beam-steering concept for use in chip-scale lidar systems, microwave photonic low-noise amplifiers (LNAs) and wideband tunable RF filters, and optical interfaces for atomic clocks and quantum sensors.
