An international research team, led by The University of Manchester’s National Graphene Institute (NGI), has developed a tunable graphene-based platform that allows for fine control over the interaction between light and matter in the terahertz (THz) spectrum, revealing rare phenomena known as exceptional points. The team also included researchers from Pennsylvania State University and Turkey's Bilkent University and Izmir Institute of Technology.
The researchers estimate that this work could advance optoelectronic technologies to better generate, control and sense light and potentially communications. They demonstrated a way to control THz waves, which exist at frequencies between those of microwaves and infrared waves. The findings could contribute to the development of beyond-5G wireless technology for high-speed communication networks.
