Using the Ehrenfest theorem for determining the self-focusing and self-trapping of nonlinear beams

Chandroth P. Jisha, Stefan Nolte, Alessandro Alberucci

We discuss how to generalize the Ehrenfest theorem for the computation of the width of nonlinear waves obeying the nonlinear Schrodinger equation. To do that, we model the nonlinea…

Spin-dependent routing of optical beams in the bulk of twisted anisotropic media

Chandroth P. Jisha, Lorenzo Marrucci, Stefan Nolte +1

We theoretically discuss a new kind of photonic spin-Hall effect (PSHE) for optical beams propagating inside an inhomogeneously twisted anisotropic material. The rotation angle pla…

Transverse Inscription of Silicon Waveguides by Picosecond Laser Pulses

Markus Blothe, Alessandro Alberucci, Namig Alasgarzade +2

In this paper, picosecond laser inscription of segmented waveguides in crystalline silicon based on a deterministic single-pulse modification process is demonstrated.Pulses of 43 p…

Application of the Green function formalism to the interplay between avalanche and multiphoton ionization induced by optical pulses

Alessandro Alberucci, Chandroth P. Jisha, Stefan Nolte

A fundamental brick of light-matter interaction at large optical intensities is the generation of a plasma. The optically-induced plasma in turn plays a fundamental role in determi…

Enhancement of third harmonic generation induced by surface lattice resonances in plasmonic metasurfaces

Jeetendra Gour, Sebastian Beer, Alessandro Alberucci +2

We investigate experimentally Third Harmonic Generation (THG) from plasmonic metasurfaces consisting of two-dimensional rectangular lattices of centrosymmetric gold nano-bars. By v…

Waveguiding driven by the Pancharatnam-Berry phase

C. P. Jisha, S. V. Arumugam, L. Marrucci +2

We theoretically and numerically investigate the properties of waveguides based on the Pancharatnam-Berry phase, obtained by a longitudinally periodic rotation of the optic axis in…
