Revolutionary Polariton-Based Microwave Device for High Performance Emission and Amplification.

Researchers at the University of Manitoba have developed a highly performing device based on cavity magnon polaritons that can emit and amplify microwaves. This device significantly outperforms previously proposed solid-state devices for coherent microwave emission and amplification at room temperature. The new gain-driven polariton realized by the researchers could open exciting new possibilities for the development of highly performing solid-state microwave sources that can be integrated on-chip. These polariton microwave sources are frequency tunable due to the fabulous controllability of light-matter interaction and could ultimately be integrated in a broad range of technologies and devices, including wireless communication systems and quantum computers.
