ROOM TEMPERATURE EXCITON-POLARITON SAGNAC INTERFEROMETER, AND RELATED METHODS

摘要

According to some embodiments of the invention, a room temperature exciton-polariton Sagnac interferometer includes a light source, an orbital angular momentum superposition state of light component configured to receive light from said light source and output an orbital angular momentum superposition state of light, and a microcavity configured to support an exciton-polariton Bose-Einstein condensate (BEC). The orbital angular momentum superposition state of light is transmitted through the microcavity to induce a vortex superposition state in the exciton-polariton BEC. The room temperature exciton-polariton Sagnac interferometer also includes a photodetector configured to detect light emitted from the microcavity, and a processor configured to determine a Sagnac phase based on the detected light.
