Autor: Vincenti, M. A., Orazio, A. D, Cappeddu, M. G., Akozbek, Neset, Bloemer, M. J., Scalora, M.

Publikováno v: Journal of Applied Physics 105, no.9 103103 (2009)

We theoretically demonstrate negative refraction and sub-wavelength resolution below the diffraction limit in the UV and extreme UV ranges using semiconductors. The metal-like re-sponse of typical semiconductors such as GaAs or GaP makes it possible

Tailoring Metallodielectric Structures for Super Resolution and Superguiding Applications in the Visible and Near IR Ranges

Autor: de Ceglia, D., Vincenti, M. A., Cappeddu, M. G., Centini, M., Akozbek, N., DOrazio, A., Haus, J. W., Bloemer, M. J., Scalora, M.

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 and near infrared ranges. In the resonance tunneling regime, we find t

Second harmonic generation from metallo-dielectric multilayer photonic band gap structures

Autor: Larciprete, M. C., Belardini, A., Cappeddu, M. G., de Ceglia, D., Centini, M., Fazio, E., Sibilia, C., Bloemer, M. J., Scalora, M.

We experimentally and theoretically investigate the second order nonlinear optical response of metallo-dielectric multilayer structures composed of Ag and Ta2O5 layers, deposited by magnetron sputtering. Second harmonic generation measurements were p
