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…

Test of a 34 GHz EOM laser frequency comb at ESPRESSO
Tobias M. Schmidt, Ewelina Obrzud, François Bouchy +18
Laser frequency combs (LFCs) are a promising technology for wavelength calibration of astronomical high-resolution spectrographs requiring utmost accuracy and stability, since they…
