In this Perspective, we discuss the different opportunities offered by time-modulated metasurfaces for dynamic wavefront engineering and space-time photonics. Efforts in codesigning a photonic response while taking into careful consideration the switching/tuning mechanisms, including thermal, electronic, optical, chemical, and mechanical...

Le déploiement de solutions d'imageries avancées, susceptibles de fournir aux systèmes robotiques une vision équivalente à celle de l'homme, nécessite l'acquisition rapide et précise d'images avec un large champ de vision. Etant particulièrement adaptées pour les systèmes optiques à grand champ, les métasurfaces offrent de nouvelles...

Optical metasurfaces are becoming ubiquitous optical components to mold the amplitude, the phase and the polarization properties of light beams. So far, most of these devices are passive in essence, that is, they cannot be arbitrarily reconfigured or optimized according to the user's interest and/or change in their surrounding environment. Here...
