Single Photons from Organic Molecules: Resonance Fluorescence and Emission Control
January 10th, 2017 SAMUELE GRANDI Imperial College London

The organic dye molecule dibenzoterrylene (DBT) in a crystal matrix is a promising candidate for single photon emission. At cryogenic temperatures, this system presents a narrow lifetime-limited transition in the near-infrared, with a quantum yield close to unity. Moreover, DBT molecules have been shown to act as a mediator for photon-photon interactions, by inducing a phase-shift on a passing photon when another photon is present. These features make DBT molecules a powerful tool for quantum information purposes, including use as single photon sources and controlled quantum gates. In this talk I will present our efforts towards controlling the optical properties of DBT. Using several photonic nanostructure for harnessing and enhancing its emission, with the final goal of a powerful on-chip tool for quantum information and communication purposes.
