Multipath dispersion and fluorescent light interference are two major problems in indoor wireless infrared communications systems. Multipath dispersion introduces intersymhol interference at data r a t e s above 10 Mhis, while fluorescent light induces severe narrowband interference to baseband modulation schemes commonly used such as OOK and PPM. This article reviews the research into the appl...

Standing modes of light in front of the reflecting surface of silicon modulate the excitation and emission of fluorescent dyes. This effect was used to determine the distance of a biomembrane from an oxidized silicon chip. The membrane of a red blood cell (ghost) was stained with a cyanine dye and attached with poly-lysine to a surface structured with microscopic steps of silicon dioxide on sil...

The visibilities of second-order ~one-photon! and fourth-order ~two-photon! interference have been observed in a Young’s double-slit experiment using light generated by spontaneous parametric down-conversion and a photon-counting intensified charge-coupled device camera. Coherence and entanglement underlie oneand two-photon interference, respectively. As the effective source size is increased, ...

Abstract We demonstrate the distance sensitivity of thermal light second-order interference beyond spatial coherence. This kind interference, emerging from measurement correlation between intensity fluctuations on two detectors, is sensitive to distances separating a remote mask source and detector, even when such information cannot be retrieved by first-order measurements. show how intimately ...
