Abstract

Photonic integration offers great potentialities for the realization of compact, light-weight, and low-cost systems for free-space applications, noteworthy in the field of 3D imaging and optical communications. However, several shortcomings still limit the widespread applicability of integrated solution, e.g., low efficiencies, narrow operational bandwidth, and polarization sensitivity. The use of metamaterial and metasurfaces, combined with innovative design approaches, represents a powerful tool to overcome these limitations. In this talk, we will present our recent advances in the realization of highly-performing devices for free-space applications and optical beam control, with a particular focus on integrated grating antennas based on metamaterials and metasurfaces.
