Microcavity resonance is demonstrated in nanocrystal quantum dot fluorescence in a one-dimensional (1D) chiral photonic bandgap cholesteric-liquid crystal host under cw excitation. The resonance demonstrates coupling between quantum dot fluorescence and the cholesteric microcavity. Observed at a band edge of a photonic stop band, this resonance has circular(More)

A single-photon source based on single CdSe quantum-dot fluorescence in a chiral-photonicbandgap liquid-crystal host manifests itself in observed fluorescence antibunching. Single quantum-dot fluorescence imaging inside different types of organic photonic bandgap microcavities is also presented. ©2007 Optical Society of America OCIS codes: (270.5290) Photon(More)
We present the measured reflectances (Beamline 6.3.2, ALS at LBNL) of naturally oxidized uranium and naturally oxidized nickel thin films from 100-460 eV (2.7 to 11.6 nm) at 5 and 15 degrees grazing incidence. These show that uranium, as UO2, can fulfill its promise as the highest known single surface reflector for this portion of the soft x-ray region,(More)
A single-photon source on demand based on single CdSe quantum-dot fluorescence in a chiralphotonic-bandgap liquid-crystal microcavity manifests itself in observed fluorescence antibunching. The aligned liquid crystal host also provides deterministically polarized fluorescence of single emitters. ©2007 Optical Society of America OCIS codes: (270.5290) Photon(More)
