DETAILED NOTES ON PPKTP CRYSTAL

We have acquired SPDC810 and hoped to work with polarization-entangled photons to start with. But it seems this device does not have polarization-entangled photons. I wonder if you might update/modify our SPDC810 to make it emit entangled photons.The spectral brightness would be the pair-generation level for each optical pump power P per photon ban
