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...

We present a simulation-based performance assessment of various phase-change materials (PCMs) in the context of photonic integrated circuits. We study a device consisting of a thin rectangular patch of PCM deposited on a silicon nitride waveguide. This device is programmed using guided optical pulses to alter its optical transmission by...
