Breakthrough in Controlling the Transmission of Light

Science Daily, 2.8.18

In a Nature Electronics cover-story paper, Andrea Alu, director of the Photonics Initiative at the Advance Science Research Center at The Graduate Center of The City University of New York, and his research team detail how they coupled two types of nonlinear resonators to isolate and force light waves to transmit in a single direction. The device enabled to light waves to overcome a law of physics that forces them to transmit identically in opposite directions. The nonlinear resonators use broad bandwidth more efficiently, make signal transmission more reliable, and use less device real estate than traditional wave isolators.
