Abstract

Phase change materials (PCM) provide unique optical characteristics such as a dramatic change in optical refractive index greater than 1, not obtainable from conventional semiconductor optical materials such as Si and InP. Thus, the PCM is being explored to program and reconfigure optical devices to adapt to the sensing needs per environment. Also, the non-volatile nature of PCM devices offers its system integration without disturbing the sensing. Here, we report on a new solid-state optical modulator device with SbTe PCM operating in the infrared range and at cryogenic temperatures with excellent switching cycle reliability for the programming of PCM-based optical devices.
