A high-performance quantum pulse gate in thin-film lithium niobate
Silia Babel, Alejandra Alarcón, Laura Serino +10
In this work, we demonstrate a quantum pulse gate (QPG) in thin-film lithium niobate. QPGs enable the selective manipulation and detection of temporal modes of quantum light and fo…

Optimizing Ultra-Long Continuous Wafer-Scale Periodic Poling in Thin-Film Lithium Niobate
Laura Bollmers, Noah Spiegelberg, Michael Rüsing +3
Periodically poled thin-film lithium niobate (TFLN) crystals are the fundamental building block for highly-efficient quantum light sources and frequency converters. The efficiency…

A ultrabright, two-colour photon pair source based on thin-film lithium niobate for bridging visible and telecom wavelengths
Silia Babel, Laura Bollmers, Franz Roeder +9
We present the design and characterisation of a guided-wave, bright and highly frequency non-degenerate parametric down-conversion source in thin-film lithium niobate. The source g…
