Role of commensurate arrangements in the optical response of metallic gratings
A. Barbara, J. Le Perchec, P. Quemerais +4
Light localization on commensurate arrangements of metallic sub-wavelength grooves is studied. We theoretically show that as the degree of commensuration tends to an irrational num…
Why metallic surfaces with grooves a few nanometers deep and wide may strongly absorb visible light
J. Le Perchec, P. Quemerais, A. Barbara +1
It is theoretically shown that nanometric silver lamellar gratings present very strong visible light absorption inside the grooves, leading to electric field intensities by several…
Controlling Strong Electromagnetic Fields at a Sub-Wavelength Scale
J. Le Perchec, P. Quemerais, A. Barbara +1
We investigate the optical response of two sub-wavelength grooves on a metallic screen, separated by a sub-wavelength distance. We show that the Fabry-Perot-like mode, already obse…
Efficient excitation of cavity resonances of subwavelength metallic gratings
P. Quemerais, A. Barbara, J. Leperchec +1
One dimensional rectangular metallic gratings enable enhanced transmission of light for specific resonance frequencies. Two kinds of modes participating to enhanced transmission ha…
