Demonstration of a polarization-entangled photon-pair source based on phase-modulated PPLN
{{output}}
We develop and demonstrate a source of polarization-entangled photon pairs using spontaneous parametric down-conversion (SPDC) in domain-engineered, periodically poled lithium niobate (PPLN) at telecom wavelengths. Pumped at 775 nm, this domain-engineered type... ...
