Abstract :
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.
