Nonlocal gap solitons in PT-symmetric periodic potentials with defocusing nonlinearity
Chandroth P. Jisha, Alessandro Alberucci, Valeriy A. Brazhnyi +1
Existence and stability of PT-symmetric gap solitons in a periodic structure with defocusing nonlocal nonlinearity are studied both theoretically and numerically. We find that, for…
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…
Anomalous diffraction in hyperbolic materials
Alessandro Alberucci, Chandroth Pannian Jisha, Allan D. Boardman +1
We demonstrate that light is subject to anomalous (i.e., negative) diffraction when propagating in the presence of hyperbolic dispersion. We show that light propagation in hyperbol…
Interplay between diffraction and the Pancharatnam-Berry phase in inhomogeneously twisted anisotropic media
Chandroth Pannian Jisha, Alessandro Alberucci, Lorenzo Marrucci +1
We discuss the propagation of an electromagnetic field in an inhomogeneously anisotropic material where the optic axis is rotated in the transverse plane but is invariant along the…
Electromagnetic confinement via spin-orbit interaction in anisotropic dielectrics
Alessandro Alberucci, Chandroth Pannian Jisha, Lorenzo Marrucci +1
We investigate electromagnetic propagation in uniaxial dielectrics with a transversely varying orientation of the optic axis, the latter staying orthogonal everywhere to the propag…
