Phase change materials based nanophotonics: multiphysics analysis

Abstract

The demand for reconfigurable components in neuromorphic computing, quantum computing and nanophotonics has led to a growing interest in active integrated photonic components. Phase change materials change their physical properties through reversible phase transitions, making them ideal for light manipulation. By altering the material's phase near a localized electromagnetic element, it is possible to achieve non-volatile, reconfigurable, and programmable functionality. However, this results in time-dependent inhomogeneous changes of physical properties, requiring a self-consistent description of electromagnetic, carrier transport, thermal, and phase transition processes. This presentation covers recent developments and applications of multiphysics simulations for phase change material-based nanophotonics.
