Backward-Wave Difference-Frequency Generation in Thin-Film Lithium Niobate
Yesim Koyaz, Ozan Yakar, Furkan Ayhan +3
Second-order nonlinear processes involving counter-propagating light generation have been explored for quantum applications and optical parametric oscillators. However, realizing t…
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…
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…
