Abstract

Metasurfaces are artificial optical interfaces designed to control the phase, the amplitude, and the polarization of an optical wavefront. They use physical mechanisms that rely on the coherent scattering of light by nano-scatterers of various shapes and material compositions. In this presentation, I will talk about on-chip integrations of metasurfaces, including lasers, LiDAR and detector arrays, and discuss how these innovative functionalities push the frontiers of optoelectronic systems beyond conventional devices. I will present new imaging capabilities provided by 3D LiDAR metasystem, emphasizing on the unprecedented performances achieved, in terms of frame rate, field of view and the simultaneous acquisition of multiple field of views. Finally, i will present our results on 3D insect-inspired directional imaging devices. We show that mimicking the peripheral vision of insect using planar metalens arrays, we could measure simultaneously the light coming from several directions to reconstruct 3D images. I will conclude this seminar by drawing perspectives and highlighting the opportunities that this field of research still has to offer, both from fundamental and application.
