Widely non-degenerate nonlinear frequency conversion in cryogenic titanium in-diffused lithium niobate waveguides
Nina Amelie Lange, Sebastian Lengeling, Philipp Mues +6
The titanium in-diffused lithium niobate waveguide platform is well-established for reliable prototyping and packaging of many quantum photonic components at room temperature. Neve…
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…
Harnessing of temporal dispersion for integrated pump filtering in spontaneous heralded single-photon generation processes
Julian Brockmeier, Timon Schapeler, Nina Amelie Lange +4
Cointegration of heralded single-photon generation and on-chip detection requires the ability to differentiate between pump light and single photons. We explored the dispersion-ind…
Pyroelectric Influence on Lithium Niobate During the Thermal Transition for Cryogenic Integrated Photonics
Frederik Thiele, Thomas Hummel, Nina Amelie Lange +8
Lithium niobate has emerged as a promising platform for integrated quantum optics, enabling efficient generation, manipulation, and detection of quantum states of light. However, i…
Fully guided and phase locked Ti:PPLN waveguide squeezing for applications in quantum sensing
Renato Domeneguetti, Michael Stefszky, Harald Herrmann +4
This work reports a fully guided setup for single-mode squeezing generation on integrated titanium-indiffused periodically poled nonlinear resonators. A continuous wave laser beam…
Fiber-coupled plug-and-play heralded single photon source based on Ti:LiNbO and polymer technology
Christian Kießler, Hauke Conradi, Moritz Kleinert +3
A reliable, but cost-effective generation of single-photon states is key for practical quantum communication systems. For real-world deployment, waveguide sources offer optimum com…
