Engineering a microheater hotspot allows for spatially resolved and repeatable multi-level switching of phase change materials in foundry-processed silicon photonics

Stochastic nucleation prevents the repeatable multi-level response of electrically-switched phase change materials in integrated photonics. In this new Nature Communications paper (https://rdcu.be/elkQJ), we circumvent this issue using deterministic amorphization via spatially controlled microheater hotspots. All using BEOL integration to foundry-processed chips. We are thankful to our collaborators: Nathan Youngblood, JJ Hu, Georges Pavlidis, Steven Vitale
