Room temperature single-photon source: single-dye molecule fluorescence in liquid crystal host

Svetlana G. Lukishova, Ansgar W. Schmid, Andrew J. McNamara +2 more

We report on new approaches toward an implementation of an efficient, room temperature, deterministically polarized, single-photon source (SPS) on demand-a key hardware element for quantum information and quantum communication. Operation of a room temperature SPS is demonstrated via photon antibunching in the fluorescence from single terrylene-dye molecules embedded in a cholesteric liquid crystal host. Using oxygen-depleted liquid crystal hosts, dye-bleaching was avoided over the course of more than 1 h of continuous 532-nm excitation. Liquid crystal hosts (including liquid crystal oligomers/polymers) permit further increase of the efficiency of the source: 1) by aligning the dye molecules along a direction preferable for maximum excitation efficiency; 2) by tuning a one-dimensional (1-D) photonic-band-gap microcavity of planar-aligned cholesteric (chiral nematic) liquid crystal layer to the dye fluorescence band.

Efficient room temperature single-photon source for quantum information: Single dye molecule fluorescence in photonic-band-gap cholesteric liquid crystal host

Operation of a single photon source for quantum information technology is demonstrated via photon antibunching in the fluorescence of single terrylene molecules embedded in a cholesteric host. The use of a one-dimensional photonic band-gap of planar aligned cholesteric layers will allow further increase in the source efficiency.

Efficient room-temperature source of polarized single photons

Svetlana G. Lukishova

An efficient technique for producing deterministically polarized single photons uses liquid-crystal hosts of either monomeric or oligomeric/polymeric form to preferentially align the single emitters for maximum excitation efficiency. Deterministic molecular alignment also provides deterministically polarized output photons; using planar-aligned cholesteric liquid crystal hosts as 1-D photonic-band-gap microcavities tunable to the emitter fluorescence band to increase source efficiency, using liquid crystal technology to prevent emitter bleaching. Emitters comprise soluble dyes, inorganic nanocrystals or trivalent rare-earth chelates.
