Photorefraction Management in Lithium Niobate Waveguides: High-Temperature vs. Cryogenic Solutions
Nina A. Lange, René Pollmann, Michael Rüsing +7
Lithium niobate sees widespread use in nonlinear and quantum optical devices, such as for sum- and difference-frequency generation or spontaneous parametric down-conversion. In lit…
Integrated, bright, broadband parametric down-conversion source for quantum metrology and spectroscopy
René Pollmann, Franz Roeder, Victor Quiring +4
Broadband quantum light is a vital resource for quantum metrology and spectroscopy applications such as quantum optical coherence tomography or entangled two photon absorption. For…
Measurement of ultrashort bi-photon correlation times with an integrated two-colour broadband SU(1,1)-interferometer
F. Roeder, R. Pollmann, M. Stefszky +7
The bi-photon correlation time, a measure for the conditional uncertainty in the temporal arrival of two photons from a photon pair source, is a key performance identifier for many…
Realization of a multi-output quantum pulse gate for decoding high-dimensional temporal modes of single-photon states
Laura Serino, Jano Gil-Lopez, Michael Stefszky +4
Temporal modes (TMs) of photons provide an appealing high-dimensional encoding basis for quantum information. While techniques to generate TM states have been established, high-dim…
Cryogenic electro-optic modulation in titanium in-diffused lithium niobate waveguides
Frederik Thiele, Felix vom Bruch, Julian Brockmeier +9
Lithium niobate is a promising platform for integrated quantum optics. In this platform we aim to efficiently manipulate and detect quantum states by combining superconducting sing…
Cryogenic integrated spontaneous parametric down-conversion
Nina Amelie Lange, Jan Philipp Höpker, Raimund Ricken +4
Scalable quantum photonics relies on interfacing many optical components under mutually compatible operating conditions. To that end, we demonstrate that spontaneous parametric dow…
