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…
Properties of entangled photon pairs generated in one-dimensional nonlinear photonic-band-gap structures
Jan Perina, Marco Centini, Concita Sibilia +2
We have developed a rigorous quantum model of spontaneous parametric down-conversion in a nonlinear 1D photonic-band-gap structure based upon expansion of the field into monochroma…
