Journal ArticleDOI
Gain-assisted superluminal light propagation
TL;DR: Gain-assisted linear anomalous dispersion is used to demonstrate superluminal light propagation in atomic caesium gas and is observed to be a direct consequence of classical interference between its different frequency components in an anomalously dispersion region.
Journal ArticleDOI
Induced coherence and indistinguishability in optical interference.
TL;DR: The interpretation of second-order interference in the superposition of signal photons from two coherently pumped parametric down-converters is discussed in terms of the intrinsic indistinguishability of the photon paths.
Journal ArticleDOI
Transparent anomalous dispersion and superluminal light-pulse propagation at a negative group velocity
TL;DR: In this article, it was shown that a superluminal light-pulse propagation can be observed even at a negative 7group velocity through a transparent medium with almost no pulse distortion.
Journal ArticleDOI
Induced coherence without induced emission
TL;DR: In this article, an interference experiment with signal and idler photons produced by parametric down-conversion in two nonlinear crystals is described and analyzed theoretically, and the implications for the interpretation of the quantum state vector are discussed, leading to the conclusion that the state reflects not only what is known, but to some extent also what is knowable in principle.
Journal ArticleDOI
