Effect of phase and spatial distinguishability of photon pairs on the entanglement fidelity
(SPIE, 2021)Polarization entanglement based cryptography uses the photon pairs generated in a spontaneous parametric down-conversion process and guarantees the security through the violation of Bell's inequality. Certain experimental ... -
Efficient coupling of down-converted photon pairs into single mode fiber
(Elsevier, 2021-08-15)We present the analysis of the down-conversion emission profile from a critically phase-matched type-I nonlinear crystal. The emission profile of the down-conversion modes shows asymmetry in cylindrical coordinate system ...
