Abstract
The realization of an ultrabright source of polarization-entangled photons using type-II phase matching in the spontaneous parametric down-conversion (SPDC) process in two-cascaded crystals was discussed. It was found the optical axes of the crystals were aligned in such a way that the extraordinary polarized cone from one crystal overlapped with the ordinarily polarized cone from the second crystal. The analysis suggested the use of suitable optical delay lines for entanglement of photon pairs originating from any conjugate points on the output cones.
