Density matrix of a single photon produced in parametric down conversion derived
arXiv:0904.4920 · doi:10.1103/PhysRevA.80.015801
Abstract
We introduce an effective numerical method of density matrix determination of fiber coupled single photon generated in process of spontaneous parametric down conversion in type I non-collinear configuration. The presented theory has been successfully applied in case of source exploited in Phys. Rev. Lett. 99, 123601 (2007) to demonstrate the experimental characterization of spectral state of single photon.
