Wide-band optical field concentrator for low-index core propagation
D. de Ceglia, M. De Sario, A. D'Orazio +4
We propose a novel chirped structure consisting of a low index polymer core bounded by modulated multilayer claddings, to realize an optical field concentrator with virtually zero…
An algorithm for constructing some maximal arcs in $\PG(2,q^2)$
A. Aguglia, L. Giuzzi
In 1974, J. Thas constructed a new class of maximal arcs for the Desarguesian plane of order . The construction relied upon the existence of a regular spread of tangent lines…
On a "zero mass" nonlinear Schrodinger equation
Antonio Azzollini, Alessio Pomponio
We look for positive solutions to the nonlinear Schrodinger equation with a potential, under the hypothesis of zero mass on the nonlinearity, in a particular situation. Existence a…
Analysis of second harmonic generation in photonic-crystal-assisted waveguides
Antonella D'Orazio, Domenico de Ceglia, Marco De Sario +3
We study second harmonic generation in a planar dielectric waveguide having a low-index, polymer core layer, bounded by two multilayer stacks. This geometry allows exceptionally st…
Gap solitons in a nonlinear quadratic negative index cavity
Michael Scalora, Domenico de Ceglia, Giuseppe D'Aguanno +4
By integrating the full Maxwell's equations we predict the existence of gap solitons in a quadratic, Fabry-Perot negative index cavity. An intense, fundamental pump pulse shifts th…
Single--peaks for a magnetic Schrödinger equation with critic al growth
S. Barile, S. Cingolani, S. Secchi
We prove existence results of complex-valued solutions for a semilinear Schrödinger equation with critical growth under the perturbation of an external electromagnetic field. Solut…
