“…Anthracene makes an excellent host because it is transparent at 700-800nm, and all its electronically excited levels lie above the S 1 levels of DBT, making it impossible for the DBT to exchange electronic excitation with its host [26,[30][31][32][33]. Moreover, DBT is highly photostable at room temperature when it is embedded in a crystal of anthracene [34,35].…”

A reliable single photon source is required for many aspects of quantum technology. Organic molecules are attractive for this application because they can have high quantum yield and can be photostable, even at room temperature. To generate a photon with high probability, a laser must excite the molecule efficiently. We develop a simple model for that efficiency and discuss how to optimise it. We demonstrate the validity of our model through experiments on a single dibenzoterrylene (DBT) molecule in an anthracene crystal. We show that the excitation probability cannot exceed 75% at room temperature, but can increase to over 99% if the sample is cooled to liquid nitrogen temperature. The possibility of high photon generation efficiency with only modest cooling is a significant step towards a reliable photon source that is simple and practical.

“…These results have important implications for numerous quantum technology applications where an efficient source of coherently scattered photons is needed as a resource [39,40]. We stress that although our calculations have been formulated in the context of QDs, the results are expected to be applicable to a variety of solid-state emitters, including nitrogen vacancy centers [60], superconducting qubits, and dye molecules embedded in crystalline lattices [61,62].…”

Under these conditions it is expected that photons are coherently scattered, and so benefit from a substantial suppression of detrimental interactions between the source and its surrounding environment. Nevertheless, we demonstrate here that this reasoning is incomplete, as phonon interactions continue to play a crucial role in determining solid-state emission characteristics even for very weak excitation. We find that the sideband resulting from non-Markovian relaxation of the phonon environment is excitation strength independent. It thus leads to an intrinsic limit to the fraction of coherently scattered light and to the visibility of two-photon coalescence at weak driving, both of which are absent for atomic systems or within simpler Markovian treatments.

Effects of Changing Substituents on the Non-Linear Optical Properties of Two Coumarin Derivatives

et al. 2017

Abstract:In this article, we study the electric properties of two coumarin derivatives whose difference stems from the change of substituents at 3-position of the pendant benzene ring (C 18 H 15 NO 3 ) and (C 18 H 15 NO 4 ). We use the supermolecule approach to deal with the molecules under the effect of the crystalline environment to calculate dipole moment, linear polarizability, and second-order hyperpolarizability, for the isolated and embedded molecules, including the static and dynamic cases and the presence of solvents. The (hyper) polarizabilities were derived from an iterative process and an ab initio computational procedure. In addition, we also calculated the HOMO-LUMO energies; at this point, the objective is to verify the effect of the exchange of substituents on the Band-Gap energy, an important parameter related to the excitation properties of coumarin compounds.
