Tailoring Metallodielectric Structures for Super Resolution and Superguiding Applications in the Visible and Near IR Ranges
D. de Ceglia, M. A. Vincenti, M. G. Cappeddu +6
We discuss propagation effects in realistic, transparent, metallo-dielectric photonic band gap structures in the context of negative refraction and super-resolution in the visible…
Second harmonic generation from metallo-dielectric multilayer photonic band gap structures
M. C. Larciprete, A. Belardini, M. G. Cappeddu +6
We experimentally and theoretically investigate the second order nonlinear optical response of metallo-dielectric multilayer structures composed of Ag and Ta2O5 layers, deposited b…
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…
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…
