Reprogrammable Nanophotonic and Metaphotonic Devices Enabled by Phase-Change Materials

A new platform for miniaturized programmable nanophotonics through integration of dielectric, semiconductor, and plasmonic materials with nonvolatile phase-change materials will be discussed. This platform enables reconfigurable photonic building blocks with subwavelength features. Two groups of reconfigurable devices based on integrated photonic structures and metasurfaces along with their unique features for state-of-the-art applications will be discussed. Design, fabrication, and application of this platform for state-of-the-art devices and systems will be covered.
