Single Photon Source on Demand Based on Single-Colloidal-Quantum-Dot Fluorescence in Chiral Photonic Bandgap Liquid Crystal Hosts

摘要

A single-photon source based on single CdSe quantum-dot fluorescence in a chiral-photonic-bandgap liquid-crystal host manifests itself in observed fluorescence antibunching. Chiral-photonic-bandgap structures will provide deterministically handed, circular-polarized fluorescence, even for emitters without a dipole moment.
