A periodic texture on the exit side of a single aperture in a metal film is created and, when combined with enhanced transmission, suggests that a wide range of photonic applications is possible.Abstract:
Light usually diffracts in all directions when it emerges from a subwavelength aperture, which puts a lower limit on the size of features that can be used in photonics. This limitation can be overcome by creating a periodic texture on the exit side of a single aperture in a metal film. The transmitted light emerges from the aperture as a beam with a small angular divergence (approximately ±3°) whose directionality can be controlled. This finding is especially surprising, considering that the radiating region is mainly confined to an area with lateral dimensions comparable to the wavelength of the light. The device occupies no more than one cubic micrometer and, when combined with enhanced transmission, suggests that a wide range of photonic applications is possible.read more

Surface plasmon subwavelength optics
TL;DR: By altering the structure of a metal's surface, the properties of surface plasmons—in particular their interaction with light—can be tailored, which could lead to miniaturized photonic circuits with length scales that are much smaller than those currently achieved.

Sub-Diffraction-Limited Optical Imaging with a Silver Superlens
TL;DR: This work demonstrated sub–diffraction-limited imaging with 60-nanometer half-pitch resolution, or one-sixth of the illumination wavelength, using silver as a natural optical superlens and showed that arbitrary nanostructures can be imaged with good fidelity.

Extraordinary optical transmission through sub-wavelength hole arrays

TL;DR: 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.

TL;DR: A fully three-dimensional theoretical study of the extraordinary transmission of light through subwavelength hole arrays in optically thick metal films shows that the enhancement of transmission is due to tunneling through surface plasmons formed on each metal-dielectric interface.

Surface plasmons enhance optical transmission through subwavelength holes
TL;DR: In this article, it was shown that the minima are the collection of loci for Wood's anomaly, which occurs when a diffracted beam becomes tangent to the film, and that the maxima were the result of a resonant excitation of surface plasmons (SP's).

TL;DR: It is demonstrated that by introducing a periodic microstructure into such a polar material (SiC) a thermal infrared source can be fabricated that is coherent over large distances (many wavelengths) and radiates in well defined directions.
