Parametric down-conversion (PDC) and frequency conversion (FC) are two of the most common nonlinear processes used in quantum optics. In the first process a nonlinear crystal is used to down convert photons from a pump laser into pairs of photons correlated by energy and linear momentum conservation constraints. In the second process, the frequency of photons is increased or decreased after...

Entangled photons are a very useful resource for quantum optics experiments. Entanglement is usually obtained through nonlinear parametric effects, such as modulation instabilities in optical fibres. We show that the coherence properties of the pump laser greatly affects the efficiency of third-order parametric effects. We present a model for incoherent nonlinear processes in optical fibres...

Invited Speaker / Conférencier invité
Nonlinear polarizations described by the χ(2) and χ(3) susceptibilities are central to many of the phenomena of classical nonlinear optics, including processes as diverse as second harmonic generation and four-wave mixing. These same susceptibilities govern quantum optical processes in which correlated photons are generated, such as spontaneous parametric down-conversion and spontaneous...

Wave-particle duality, superposition and entanglement are among the most counterintuitive
features of quantum theory. They clash with conventional classical wisdom and motivate
the construction of hidden-variable theories. Here I point out that realism
(defined as a property of photons being either particles or waves, but not both) is
incompatible with determinism provided superluminal...
