Transverse power flow reversing of confined waves in extreme nonlinear metamaterials
A. Ciattoni, C. Rizza, E. Palange
We theoretically prove that electromagnetic beams propagating through a nonlinear cubic metamaterial can exhibit a power flow whose direction reverses its sign along the transverse…

Mapping the nonlinear optical susceptibility by noncollinear second harmonic generation
M. C. Larciprete, F. A. Bovino, M. Giardina +6
We present a method, based on noncollinear second harmonic generation, to evaluate the non-zero elements of the nonlinear optical susceptibility. At a fixed incidence angle, the ge…

Efficient generation and sorting of orbital angular momentum eigenmodes of light by thermally tuned q-plates
Ebrahim Karimi, Bruno Piccirillo, Eleonora Nagali +2
We present methods for generating and for sorting specific orbital angular momentum (OAM) eigenmodes of a light beam with high efficiency, using a liquid crystal birefringent plate…
