Breakthrough in Logic Control of Exciton-Polaritons

Exciton-polaritons are part-light, part-matter particles that exist in semiconductors and have huge potential for photonic circuits. In a recent study, NYU-ECNU Institute of Physics members and collaborators have implemented the full set of logical gate functionalities (temporal AND, OR and NOT gates) in localized exciton polaritons at room temperature. The polariton logic gates demonstrate advantages in ultrafast switching, universality and simplified compatibility, showing great potential for building polariton logic networks. The outcome has been published in a Nature Photonics article titled “All-optical temporal logic gates in localized exciton polaritons.” The research is a collaboration between ECNU faculty Professor Hui Li, Professor Jian Wu and NYU Shanghai Associate Professor of Physics Tim Byrnes. Professor Wu and Professor Byrnes are also associated members of the NYU-ECNU Institute of Physics at NYU Shanghai.
