Power-efficient silicon nitride soliton microcombs

Microcombs are strong contenders for attaining the frequency stability and performance of standard passively modelocked lasers on a chip scale. Understanding the optical phase noise dynamics in soliton microcombs and enhancing the power efficiency are crucial directions for the development of ultra-low timing jitter pulsed sources on-chip with enhanced repetition rate stability and ultra-low optical linewidth.

A Particle Accelerator on a Photonic Chip: Design and Applications

Microwave-powered accelerators are widespread in science, medicine and industry. We just demonstrated the photonic version on a chip, which accelerates and confines electrons in a channel of silicon nanopillars, enabling new chip-based radiation tools.

New integrated LiDAR technology using chip-integrated beam steering and frequency-angular imaging

We report an on-chip, acousto-optic beam steering technique that uses only a single gigahertz acoustic transducer to steer light beams into free space. Exploiting the physics of Brillouin scattering, where beams steered at different angles are labeled with unique frequency shifts, this technique uses a single coherent receiver to resolve an object’s angular position in the frequency domain and enables frequency-angular resolving (FAR) LiDAR.
