Nonlinear and Quantum Optics with Whispering Gallery Resonators [PDF]
, 2016 Optical Whispering Gallery Modes (WGMs) derive their name from a famous acoustic phenomenon of guiding a wave by a curved boundary observed nearly a century ago. This phenomenon has a rather general nature, equally applicable to sound and all other waves.

Single-Cycle Nonlinear Optics [PDF]
Science, 2008 Nonlinear optics plays a central role in the advancement of optical science and laser-based technologies. We report on the confinement of the nonlinear interaction of light with matter to a single wave cycle and demonstrate its utility for time-resolved and strong-field science.

Ultrashort Vortex Pulses with Controlled Spectral Gouy Rotation
Applied Sciences, 2020 Recently, the spatio-spectral propagation dynamic of ultrashort-pulsed vortex beams was demonstrated by 2D mapping of spectral moments. The rotation of characteristic anomalies, so-called “spectral eyes”, was explained by wavelength-dependent Gouy phase ...

Fast and accurate modelling of nonlinear pulse propagation in graded-index multimode fibers [PDF]
, 2017 We develop a model for the description of nonlinear pulse propagation in multimode optical fibers with a parabolic refractive index profile. It consists in a 1+1D generalized nonlinear Schr\"odinger equation with a periodic nonlinear coefficient, which ...

Decoupling frequencies, amplitudes and phases in nonlinear optics [PDF]
, 2017 In linear optics, light fields do not mutually interact in a medium. However, they do mix when their field strength becomes comparable to electron binding energies in the so-called nonlinear optical regime.
