Ultrabright Sagnac-type source of non-degenerate polarization-entangled photon pairs using only off-the-shelf optical components

We develop a Sagnac-type source of ultrabright, non-degenerate, polarization-entangled photon pair that is highly stable and compact simultaneously. We use a \(20~\text{mm}\) long PPLN bulk crystal which, upon pumping continuously with \(532~\text{nm}\) wavelength, produces polarization-entangled ph...
