Single Spatio-Temporal Mode Bright Twin-Beam Source Across the Near- and Mid-Infrared
Gabriel Demontigny, Patrick Cusson, Amauri Perraton Elorza +6
We introduce an ultrafast, bright, entangled twin-beam source generated by type-0 parametric down-conversion in periodically-poled lithium niobate at MHz repetition rate, with cont…

Spontaneous four-wave mixing in a thin layer with second-order nonlinearity
Changjin Son, Maria Chekhova
Pairs of entangled photons are crucial for photonic quantum technologies. The demand for integrability and multi-functionality suggests 'flat' platforms - ultrathin layers and meta…
