We experimentally demonstrate the spatial self-cleaning of a highly multimode optical beam, in the process of second-harmonic generation in a quadratic nonlinear potassium titanyl phosphate crystal. As the beam energy grows larger, the output beam fr

Manipulating light at the nanoscale by means of dielectric nanoantennas recently received renewed attention thanks to the development of key enabling fabrication tools in semiconductor technology, combined with the extremely low losses exhibited by d

By employing an iterative procedure based on a bidirectional beam propagation method, we develop a numerical algorithm to model light propagation in multilayered structures with second-order nonlinearities. Examples of the applicability of this techn

International audience; We show that second-harmonic generation in the regime of weak dispersion/diffraction can exhibit a coexistence of wave breaking mechanisms, such that a gradient catastrophe yielding a dispersive shock wave competes with modula

Scaling laws of second-harmonic generation (SHG) in nonlinear Bragg stacks (or finite one-dimensional photonic crystals) as a function of the number N of periods are explored. While it is known that SHG scales like the sixth power of N when phase mat

We characterize the Hopf bifurcations that rule self-pulsing of spatially varying fields in distributed feedback structures with Kerr nonlinear response. Our analysis allows us to distinguish, inside the stop band, between fully unstable regions and

We report on the characterization of periodically poled lithium niobate structures grown by the off-center Czochralski technique with periods ranging between 2 and 10 mu m. The domains distribution along the crystal was inspected by a profilometer sc

We investigate backward second-harmonic generation in short-period quasi-phase-matched gratings by means of a finite-difference time-domain method adapted to modelling dispersive nonlinear propagation in the one-dimensional quasi-scalar approximation
