Pump Spectral Bandwidth, Birefringence, and Entanglement in Type-II Parametric Down Conversion

Figure 1

The concurrence as a function of the ratio of the crystal transit times difference ( 𝜏 𝑝 2 / 𝜏 𝑝 3 ) and the pump and the second down-converted photon. Note: 𝜎 𝑝 = 0 . 1 (blue [a]), 𝜎 𝑝 = 0 . 5 (red [b]), 𝜎 𝑝 = 1 . 0 (green [c]), and 𝜎 𝑝 = 4 . 0 (pink [d]).
