Tailoring polarization entanglement in anisotropy-compensated SPDC
arXiv:0710.2089 · doi:10.1103/PhysRevA.77.015805
Abstract
We show that the angular spectrum of type-II SPDC contains a continuum of maximally entangled states. For the realization of a bright source of entangled two-photon states, a standard technique is to compensate for the transverse walk-off in the production crystal. We demonstrate that polarization entangled states can be effectively engineered by generalizing this approach. Our method allows to considerably enrich the set of generated entangled states with a controlled tailoring them.
