Room-temperature ultrabright single photon sources based on colloidal quantum dots on directional resonator-antennas: towards high dimensional encoding of photonic qudits

Research output: Contribution to journalConference articlepeer-review

Abstract

We present a novel approach that overcomes the outstanding challenge of the rate-directionality tradeoff of monolithic single photon sources operating at room temperature, and demonstrate ultrabright, highly directional single photon sources based on colloidal quantum dots positioned on a hybrid nano-resonator - antenna device, that can be used for both free-space and fiber applications. We also demostrate methods for encoding high-dimensional qudits on the different spatial degrees of freedom of the photons emitted from these sources.
