Journal ArticleDOI
Dispersive properties of finite, one-dimensional photonic band gap structures : applications to nonlinear quadratic interactions
Marco Centini,Concita Sibilia,Michael Scalora,Giuseppe D'Aguanno,Mario Bertolotti,Mark J. Bloemer,Charles M. Bowden,Igor S. Nefedov +7 more
TL;DR: The concept of a complex effective index for structures of finite length, derived from a generalized dispersion equation that identically satisfies the Kramers-Kronig relations is introduced.
Journal ArticleDOI
Chirality and Chiroptical Effects in Metal Nanostructures: Fundamentals and Current Trends
Joel T. Collins,Christian Kuppe,David C. Hooper,Concita Sibilia,Marco Centini,Ventsislav K. Valev +5 more
TL;DR: In this paper, the emergence and evolution of chirality in molecules, as a function of geometrical parameters, is discussed and a survey of modern chiral materials is presented.
Journal ArticleDOI
Second- and third-harmonic generation in metal-based structures
Michael Scalora,Maria Antonietta Vincenti,Domenico de Ceglia,Vito Roppo,Marco Centini,Neset Akozbek,Mark J. Bloemer +6 more
TL;DR: In this article, a theoretical approach to the study of second and third harmonic generation from metallic structures and nanocavities filled with a nonlinear material in the ultrashort pulse regime is presented.
Journal ArticleDOI
Negative refraction and sub-wavelength focusing in the visible range using transparent metallo-dielectric stacks
Michael Scalora,Giuseppe D'Aguanno,Nadia Mattiucci,Mark J. Bloemer,Domenico de Ceglia,Marco Centini,A. Mandatori,Concita Sibilia,Neset Akozbek,Mirko Cappeddu,Mark Fowler,Joseph W. Haus +11 more
TL;DR: These results reveal that in the wavelength regime of interest evanescent waves are not transmitted by the transparent multilayer, metallo-dielectric photonic band gap structure, and that the main underlying physical mechanisms for sub-wavelength focusing are resonance tunneling, field localization, and propagation effects.
Journal ArticleDOI
Enhancement of second-harmonic generation in a one-dimensional semiconductor photonic band gap
Yannick Dumeige,Petar Vidakovic,Sébastien Sauvage,Isabelle Sagnes,Juan Ariel Levenson,Concita Sibilia,Marco Centini,Giuseppe D'Aguanno,Michael Scalora +8 more
TL;DR: In this article, the authors demonstrate significant enhancement of second-order nonlinear interactions in a one-dimensional semiconductor Bragg mirror operating as a photonic band gap structure, thanks to a simultaneous availability of a high density of states and the improvement of effective coherent length near the photonic bands edge.
