Enhancing broadband second harmonic generation in a thin film lithium niobate racetrack resonator with tunable-coupling
Olivia Hefti, Jean-Etienne Tremblay, Andrea Volpini +7
Second harmonic generation in thin film periodically poled lithium niobate (PPLN) is constrained by an efficiency-bandwidth trade-off and fabrication-sensitive scaling. We demonstr…
Fabrication-tolerant frequency conversion in thin film lithium niobate waveguide with layer-poled modal phase matching
O. Hefti, J. -E. Tremblay, A. Volpini +11
Thanks to its high quadratic nonlinear susceptibilty and low propagation losses, thin film lithium niobate (TFLN) on insulator is an ideal platform for laser frequency conversion a…
Ultrabroadband tunable difference frequency generation in standardized thin-film lithium niobate platform
Yesim Koyaz, Christian Lafforgue, Homa Zarebidaki +4
Thin-film lithium niobate (TFLN) on insulator is a promising platform for nonlinear photonic integrated circuits (PICs) due to its strong light confinement, high second-order nonli…
Ultraviolet astronomical spectrograph calibration with laser frequency combs from nanophotonic lithium niobate waveguides
Markus Ludwig, Furkan Ayhan, Tobias M. Schmidt +21
Astronomical precision spectroscopy underpins searches for life beyond Earth, direct observation of the expanding Universe and constraining the potential variability of physical co…
