Multi-wavelength Q-plate Arithmetic in an All-Liquid-Crystal Modular Setup
Jacek Piłka, Michał Kwaśny, Magdalena Czerniewicz +2
Vortex beams are a type of structured light characterized by phase rotation around the propagation axis, resulting in orbital angular momentum. Their properties make them useful in…
Reorientational solitons in nematic liquid crystals with modulated alignment
Filip A. Sala, Noel F. Smyth, Urszula A. Laudyn +3
In uniaxial soft matter with a reorientational nonlinearity, such as nematic liquid crystals, a light beam in the extraordinary polarization walks off its wavevector due to birefri…
Nonlinear continuous-wave optical propagation in nematic liquid crystals: interplay between reorientational and thermal effects
Alessandro Alberucci, Urszula A. Laudyn, Armando Piccardi +4
Thanks to their unique properties, nematic liquid crystals feature a variety of mechanisms for light-matter interactions. For continuous-wave optical excitations, the two dominant…
Super-mode spatial optical solitons in liquid crystals with competing nonlinearities
Pawel Jung, Wieslaw Krolikowski, Urszula A. Laudyn +2
We study numerically formation of spatial optical solitons in nematic liquid crystals with competing nonlocal nonlinearities. We demonstrate that at the sufficiently high input pow…
Spontaneous symmetry breaking of self-trapped and leaky modes in quasi-double-well potentials
Krzysztof B. Zegadlo, Nir Dror, Marek Trippenbach +2
We investigate competition between two phase transitions of the second kind induced by the self-attractive nonlinearity, viz., self-trapping of the leaky modes, and spontaneous sym…
Stabilization of solitons under competing nonlinearities by external potentials
Krzysztof B. Zegadlo, Tomasz Wasak, Boris A. Malomed +2
We report results of the analysis for families of one-dimensional (1D) trapped solitons, created by competing self-focusing (SF) quintic and self-defocusing (SDF) cubic nonlinear t…
