Light enhancement on thin and ultra-thin high-index dielectric slabs with rectangular nano-pits
Jerome Le Perchec
We closely study the local amplifications of visible light on a thin dielectric slab presenting a sub-wavelength array of small, rectangular, bottom-closed holes. The high-quality…

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…
