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.

Brillouin Scattering in Silicon Nitride Photonic Circuits

By invited speaker David Marpaung, Professor at Twente University, The Netherlands. He is the head of the Nonlinear Nanophotonics group and the co-chairholder of the Laser Physics and Nonlinear Optics chair. David received his Ph.D. degree in electrical engineering from the University of Twente, the Netherlands in 2009. From 2009 to 2012 he was a postdoctoral researcher in the University of Twente, working on microwave photonic system integration for optical beamforming.
