Abstract

An efficient technique for producing deterministically polarized single photons uses liquid-crystal hosts (100) 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 (102, 104) 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.

Claims

AMENDED CLAIMS [received by the International Bureau on 13 December 2004 (13.12.04); claim 127 added, original claims 1-126 unchanged (1 Page)]
120. The method of claim 119, wherein the light-emitting dye comprises a dye selected from the group consisting of terrylene, rhodamine, or a rhodamine derivative, Alexa Fluor, DiICι8(3). and DiIC]8(5). 121. The method of claim 11 , wherein the other fluorescence emitter comprises a core-shell semiconductor πanocrystal. 122. The method of claim 121, wherein the semiconductor nanocrystal comprises PbSe, CdTe, PbS, or CdS as core material 123. The method of claim 119, wherein the other fluorescence emitter comprises a trivalent rare-earth chelate. 124. The method of claim 95, in which the polarized excitation light is focussed by a reflective or transmissive focussing element into the liquid-crystal layer of the substrate/liquid-crystal/substrate sandwich such that the focal volume intercepts one and only one dye molecule or other fluorescence emitter. 125, The method of claim 95, comprising translating laterally the substrate/ljquid-crystal/substrate sandwich such that whenever a single dye molecule or other single fluorescence emitter irreversibly photobleaches, another single emitter can be moved into the excitation-light focal volume. 126. The method of claim 95, wherein the reflective or transmissive focussing element is also the optical element collecting the emitted light. 127. The source of claim 1, wherein the source is a source of determmistically polarized single photons.
