Terahertz Devices Using the Optical Activation of GeTe Phase Change Materials: Toward Fully Reconfigurable Functionalities
Abstract
Reconfigurable multifunctional terahertz (THz) devices are crucial for the development of practical applications such as high-speed communications, spectroscopy and imaging, etc. but their expansion is still requiring efficient agility functions operating in the THz domain. Chalcogenide phase change materials (PCMs) with their broadband response, non-volatile and
