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…
Breather solitons in highly nonlocal media
Alessandro Alberucci, Chandroth P. Jisha, Gaetano Assanto
We investigate the breathing of optical spatial solitons in highly nonlocal media. Generalizing the Ehrenfest theorem, we demonstrate that oscillations in beam width obey a fourth-…
