Reconfigurable nanophotonics seeks to actively control light at the nanoscale for ultrafast information processing and storage. Antimony trisulfide (Sb2S3), a phase-change material with considerable optical modulation and near-zero optical losses, is a perfect candidate for this effort. This project aims to imprint the metasurface waveguide switch into the un-patterned Sb2S3 patch by an ultrafast laser and show the low-loss redirection of light. This device could represent a new elementary unit of ultrafast photonic computing and data storage.
