A priori bounds and global bifurcation results for frequency combs modeled by the Lugiato-Lefever equation [PDF]
In nonlinear optics $2\pi$-periodic solutions $a\in C^2([0,2\pi];\mathbb{C})$ of the stationary Lugiato-Lefever equation $-d a"= ({\rm i} -\zeta)a +|a|^2a-{\rm i} f$ serve as a model for frequency combs, which are optical signals consisting of a ...

Optimized frequency comb spectrum of parametrically modulated bottle microresonators
“Previous studies investigating the creation of optical frequency combs through parametric modulation of microresonators rely on lumped-element models that do not consider how the modulations are spatially distributed.

Cavity-enhanced ultrafast two-dimensional spectroscopy using higher-order modes [PDF]
We describe methods using frequency combs and cavities for recording two-dimensional ultrafast spectroscopy signals with high sensitivity. By coupling multiple frequency combs to modes of an optical resonator, cavity-enhanced 2D spectroscopy signals are ...

Coherent phonon induced optical modulation in semiconductors at terahertz frequencies [PDF]
The coherent modulation of electronic and vibrational nonlinearities in atoms and molecular gases by intense few-cycle pulses has been used for high-harmonic generation in the soft X-ray and attosecond regime, as well as for Raman frequency combs that ...

Low-noise Yb:CALGO optical frequency comb
We report on a compact optical frequency comb, operating in the wavelength range from 670 to 1500 nm, based on diode-pumped low-noise femtosecond Yb:CALGO amplified laser system. Both the carrier-envelope offset and repetition rate are phase-locked to reference synthesizers. A full characterization of the frequency comb, in terms of frequency stability,
