-2 self-referencing for silicon nitride photonics via a heterogeneously integrated lithium niobate layer
Weichen Fan, Bastian Ruhnke, Camiel Op de Beeck +4
Heterogeneous integration combines complementary material properties in a single photonic platform. Here, we demonstrate on-chip -2 self-referencing in a heterogeneously inte…
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…
Mid-infrared continua via spectral broadening and difference frequency generation in a nanophotonic lithium niobate waveguide
Markus Ludwig, Furkan Ayhan, Thibault Voumard +5
Periodically poled thin film lithium niobate waveguides provide simultaneous access to efficient second and third order nonlinear processes, enabling broadband generation of cohere…
Spectral dynamics in broadband frequency combs with overlapping harmonics
Weichen Fan, Furkan Ayhan, Thibault Wildi +8
Optical frequency combs and their spectra of evenly spaced discrete laser lines are essential to modern time and frequency metrology. Recent advances in integrated photonic wavegui…
Supercontinua from integrated gallium nitride waveguides
Weichen Fan, Markus Ludwig, Ian Rousseau +4
Supercontinua are broadband spectra that are essential to optical spectroscopy, sensing, imaging, and metrology. They are generated from ultrashort laser pulses through nonlinear f…
