Enhanced second harmonic generation from resonant GaAs gratings
D. de Ceglia, G. D'Aguanno, N. Mattiucci +2
We study second harmonic generation in nonlinear, GaAs gratings. We find large enhancement of conversion efficiency when the pump field excites the guided mode resonances of the gr…
The nature of transmission resonances in plasmonic metallic gratings
G. D'Aguanno, N. Mattiucci, M. J. Bloemer +3
Using the Fourier modal method (FMM) we report our analysis of the transmission resonances of a plasmonic grating with sub-wavelength period and extremely narrow slits for waveleng…
Bloch vector analysis in non linear, finite, dissipative systems: an experimental study
G. D'Aguanno, M. C. Larciprete, N. Mattiucci +6
We have investigated and experimentally proved the robustness of the Bloch vector for one-dimensional, nonlinear, finite, dissipative systems. The case studied is the second harmon…
Transmission function properties for multi-layered structures: Application to super-resolution
Nadia Mattiucci, Giuseppe D'Aguanno, Michael Scalora +2
We discuss the properties of the transmission function in the k-space for a generic multi-layered structure. In particular we analytically demonstrate that a transmission greater t…
Energy considerations for a superlens based on metal/dielectric multilayers
Mark Bloemer, Giuseppe D'Aguanno, Michael Scalora +2
We investigate the resolution and absorption losses of a Ag/GaP multilayer superlens. For a fixed source to image distance the resolution is independent of the position of the lens…
Homogenization procedure for a metamaterial and local violation of the second principle of thermodynamics
Nadia Mattiucci, Giuseppe D'Aguanno, Neset Akozbek +2
Classical theory of crystals states that a medium to be considered homogeneous must satisfy the following requirements: a) the dimension of the elementary cell must be much smaller…
Influence of the losses on the super-resolution performances of an impedance matched negative index material
Giuseppe D'Aguanno, Nadia Mattiucci, Mark J. Bloemer
We discuss by a Poynting vector analysis how the losses of a negative index material (NIM) affect the resolution performances of a Veselago-Pendry lens and we analyze those perform…
Ultra-slow light pulses in a nonlinear metamaterial
Giuseppe D'Aguanno, Nadia Mattiucci, Mark J. Bloemer
We find the analytical expression for the threshold intensity necessary to launch ultra-slow light pulses in a metamaterial with simultaneous cubic electric and magnetic nonlineari…
Optical Vortices during a Super-Resolution Process in a Metamaterial
G. D'Aguanno, N. Mattiucci, M. Bloemer +1
We show that a super-resolution process with 100% visibility is characterized by the formation of a point of phase singularity in free space outside the lens in the form of a saddl…
Broadband superresolving lens with high transparency for propagating and evanescent waves in the visible range
Mark J. Bloemer, Giuseppe D'Aguanno, Nadia Mattiucci +2
We present a theoretical analysis of a super-resolving lens based on 1-dimensional metallo-dielectric photonic crystals composed of Ag/GaP multilayers. The lens contains a total of…
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…
Negative refraction and sub-wavelength imaging using transparent metal-dielectric stacks
Michael Scalora, Giuseppe D'Aguanno, Neset Akozbek +6
Negative refraction is known to occur in materials that simultaneously possess a negative electric permittivity and magnetic permeability; hence they are termed negative index mate…
