[Tu-A2-F-03] A quantum dot two-photon emitter via dark-state biexciton loading

〇Bang Wu¹, Zhiliang Yuan¹ (1. Beijing Academy of Quantum Information Science (China))

We demonstrate a high-efficiency two-photon emitter using the degenerate biexciton–exciton cascade in a Purcell-enhanced quantum dot–micropillar system. Polarization-selective p-shell excitation enables efficient biexciton loading, with stimulated emission as the key mechanism enhancing two-photon temporal correlation.
