Metasurfaces are artificial optical interfaces designed to control the phase, the amplitude and the polarization of an optical wavefront. These optical surfaces rely on the coherent scattering of light by a sizable distribution of nano-scatterers of various shapes and material compositions. Metasurfaces hold great potential for on-chip integration of photonic components, significantly promoting the development of miniaturized optoelectronic systems.

The Genevet group is working on the physics of Metasurfaces and their applications for directional light collection, emission, and LiDARs. The group recently pioneered disruptive research on the developments in topological and tunable nanophotonic systems. In this webinar hosted by the Optoelectronics Technical Group, Patrice Genevet will give a tutorial presentation of recent activities in this field. Dr. Genevet will also present the latest results on metasurface LiDAR technology and integrated laser wavefront manipulation.

About the Presenter: Patrice Genevet from CNRS

Patrice Genevet obtained his PhD at University of Nice Sophia Antipolis in France on spatial solitons in semiconductor lasers and amplifiers. After his PhD, he did five years of postdoctorate fellowship (2009-2014) in the Capasso group (Harvard University) in collaboration with Prof. Scully (Texas A&M University). In 2014, he obtained the position of senior research scientist at A*STAR, Singapore. In 2015, He joined CNRS. He is the recipient of several awards, including the Highly Cited Researcher by the Web of Science every year since 2018, the ERC starting Grant 2015, the ERC Proof of Concept 2019, the Aimé-Cotton Price 2017 from the French Physical Society, and the 2021 Fabry-de Gramont price from the French Optical Society. He serves as an associate editor for Optics Letters and Science Advances. P. Genevet research activities concern the development of metasurfaces for sensing, imaging, and LiDAR. He owns 7 patents, more than 100 publications and an H factor of 48(google scholar).
