Graphene-based perfect optical absorbers harnessing guided mode resonances
M. Grande, M. A. Vincenti, T. Stomeo +8
We numerically and experimentally investigate graphene-based optical absorbers that exploit guided mode resonances (GMRs) achieving perfect absorption over a bandwidth of few nanom…
Graphene-based absorber exploiting guided mode resonances in one-dimensional gratings
M. Grande, M. A. Vincenti, T. Stomeo +8
A one-dimensional dielectric grating, based on a simple geometry, is proposed and investigated to enhance light absorption in a monolayer graphene exploiting guided mode resonances…
Stable planar mesoscopic photonic crystal cavities
Giovanni Magno, Antoine Monmayrant, Marco Grande +4
Mesoscopic self-collimation in mesoscopic photonic crystals with high reflectivity is exploited to realize a novel high-Q factor cavity by means of mesoscopic PhC planar mirrors. T…
Experimental demonstration of a novel bio-sensing platform via plasmonic band gap formation in gold nano-patch arrays
Marco Grande, Maria Antonietta Vincenti, Tiziana Stomeo +9
We discuss the possibility of implementing a novel bio-sensing platform based on the observation of the shift of the leaky surface plasmon mode that occurs at the edge of the plasm…
Enhanced Transmission and Second Harmonic Generation from Subwavelength Slits on Metal Substrates
M. A. Vincenti, M. De Sario, V. Petruzzelli +7
We theoretically investigate second harmonic generation that originates from the nonlinear, magnetic Lorentz force term from single and multiple apertures carved on thick, opaque m…
Metallo-Dielectric Multilayer Structure for Lactose Malabsorption Diagnosis through H2 Breath Test
N. Cioffi, D. de Ceglia, M. De Sario +6
A metallo-dielectric multilayer structure is proposed as a novel approach to the analysis of lactose malabsorption. When lactose intolerance occurs, the bacterial overgrowth in the…
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…
Enhancement and Inhibition of Stimulated Processes in a Negative Index Cavity
Domenico de Ceglia, Marco Centini, Antonella D'Orazio +6
We study second harmonic generation in a negative index material cavity. The transmission spectrum shows a gap between the electric and magnetic plasma frequencies, so that localiz…
