We present an experiment addressed to verify the validity of the entanglement quantifier R, defined as the ratio between single counts and coincidence distribution width for pure biphoton states generated by short pump pulses. We demonstrate that this ratio can be efficient to estimate entanglement degree in frequency domain. Our work has been performed with a femto second pulsed laser pump add...

An effective-medium approach is used to derive a set of coupled-mode equations describing quadratic parametric interactions in a one-dimensional inhomogeneous medium of finite length. The solutions for both copropagating and counterpropagating interactions are used to study the quantum-mechanical process of spontaneous parametric down-conversion (SPDC). An example is studied in which the inhomo...
