NRL research team develops a new method to control single photon emission using a hybrid ferroelectric heterostructure. The character of light emitted from an atomic scale emitter in a monolayer semiconductor, WS2, is controlled by the ferroelectric polarization in an adjacent film. Localized emitters in the monolayer WS2 over “up-domains” in the ferroelectric film emit high purity quantum light, while those over “down-domains” emit semi-classical light. This modulation offers an additional tool for secure communications and quantum encryption schemes based upon single photon sources.

NRL Introduces a New Paradigm for Control of Quantum Emitters

WASHINGTON – A U.S. Naval Research Laboratory (NRL) multi-disciplinary team developed a new paradigm for the control of quantum emitters, providing a new method for modulating and encoding quantum photonic information on a single photon…
