Effect of polarization deviation of spontaneous parametric down-conversion on the degree of biphoton entanglement
Dmitry N. Frolovtsev, Sergey A Magnitskiy · Physics of Wave Phenomena · 2017
Analysis is given to the effect of polarization deviation due to spontaneous parametric downconversion on the states of polarization-entangled photons generated via a cascaded two-crystal geometry with type I phase matching (e−oo).
