Moore Foundation grantee Dimitri Basov and colleagues at the University of California, San Diego have found a new way to control light in crystalline materials using polaritons, which are hybrid particles that form when infrared or visible-frequency light is coupled with electric or magnetic waves.
The team's technique is particularly powerful because these polaritons can be controlled using an electronic gate. This type of switching behavior could help transmit information within tiny spaces, which is useful for high-resolution imaging of materials.
