CCNY team makes single photon switch advance
E-Mail IMAGE: Schematic of the optical microcavity with 2D semiconductor. The nonlinear optical response arises from the larger Bohr radii Rydberg excitons allowing to push the limit to few photon nonlinear limit. view more Credit: Image credit: Rezlind Bushati The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies. Realizing this in a chip-scale architecture is important for scalability, which amplifies a breakthrough by City College of New York researchers led by physicist Vinod Menon. They've dem...
