Terahertz Devices Using the Optical Activation of GeTe Phase Change Materials: Towards Fully Reconfigurable Functionalities
Maxime Pinaud, Georges Humbert, Sebastian Engelbrecht +3
We are demonstrating the optical control of a specific state of the germanium telluride (GeTe) phase change material and its integration as control element for realizing extremely…
