TLDR
In this article, the optical properties of submicrometre cylindrical cavities in metallic films were explored and it was shown that arrays of such holes display highly unusual zero-order transmission spectra at wavelengths larger than the array period, beyond which no diffraction occurs.Abstract:
The desire to use and control photons in a manner analogous to the control of electrons in solids has inspired great interest in such topics as the localization of light, microcavity quantum electrodynamics and near-field optics1,2,3,4,5,6. A fundamental constraint in manipulating light is the extremely low transmittivity of apertures smaller than the wavelength of the incident photon. While exploring the optical properties of submicrometre cylindrical cavities in metallic films, we have found that arrays of such holes display highly unusual zero-order transmission spectra (where the incident and detected light are collinear) at wavelengths larger than the array period, beyond which no diffraction occurs. In particular, sharp peaks in transmission are observed at wavelengths as large as ten times the diameter of the cylinders. At these maxima the transmission efficiency can exceed unity (when normalized to the area of the holes), which is orders of magnitude greater than predicted by standard aperture theory. Our experiments provide evidence that these unusual optical properties are due to the coupling of light with plasmons — electronic excitations — on the surface of the periodically patterned metal film. Measurements of transmission as a function of the incident light angle result in a photonic band diagram. These findings may find application in novel photonic devices.read more

TL;DR: It is shown that lyotropic optical diffraction gratings--composed of biofunctional lipid multilayers with controllable heights between approximately 5 and 100 nm--can be fabricated by lipid dip-pen nanolithography, allowing nanostructures to be interfaced by combinations of top-down and bottom-up fabrication methods.

TL;DR: In this paper, the authors analyzed the influence of the inherent finite size of the arrays and reported the unexpected spatial distribution of light as it emerges from the arrays, which can be explained by a model that takes into account the asymmetry induced by the array edges and the effects this has on the emission pattern across the arrays.
