Gaussian modeling and Schmidt modes of SPDS biphoton states
arXiv:0906.3273 · doi:10.1088/0953-4075/42/17/175503
Abstract
A double-Gaussian model and the Schmidt modes are found for the biphoton wave function characterizing spontaneous parametric down-conversion with the degenerate collinear phase-matching of the type I and with a pulsed pump. The obtained results are valid for all durations of the pump pulses, short, long and intermediately long.
