Excitation Method

The interest in quantum dots as sources of quantum light is based upon the potential for high photon generation efficiency that originates in their atom-like energy structure. Quantum dots can be excited resonantly and coherently, where generation of photon pairs calls for a specific excitation method of two-photon resonant excitation of the biexciton. Though this method is very efficient, it was very often showing sub-unity excitation efficiency that could be observed, for instance, in the maximum amplitude of the Rabi oscillations. Investigation of the dephasing processes in this excitation technique is of strategic interest for quantum communication technologies.

Photon Generation

For nanowire-based sources of non-classical light, the rate at which photons are generated and the ability to efficiently collect them are determined by the nanowire geometry. Using selective-area vapour-liquid-solid epitaxy, we show how it is possible to control the nanowire geometry and tailor it to optimise device performance. High efficiency single photon generation with negligible multi-photon emission is demonstrated using a quantum dot embedded in a nanowire having a geometry tailored to optimise both collection efficiency and emission rate.
