“…Initial reports of dramatically enhanced transmission through arrays of subwavelength holes in thin films and membranes [1][2][3] have focused attention on the physics underlying this surprising optical response. Since the early experiments were carried out on metal films, surface plasmon polaritons [4,5] were invoked to explain the anomalously high transmission and to suggest new types of photonic devices [5].…”

Investigations of the optical response of subwavelength-structure arrays milled into thin metal films have revealed surprising phenomena, including reports of unexpectedly high transmission of light. Many studies have interpreted the optical coupling to the surface in terms of the resonant excitation of surface plasmon polaritons (SPPs), but other approaches involving composite diffraction of surface evanescent waves (CDEW) have also been proposed. Here we present a series of measurements on very simple one-dimensional subwavelength structures to test the key properties of the surface waves, and compare them to the CDEW and SPP models. We find that the optical response of the silver metal surface proceeds in two steps: a diffractive perturbation in the immediate vicinity (2–3 mu m) of the structure, followed by excitation of a persistent surface wave that propagates over tens of micrometres. The measured wavelength and phase of this persistent wave are significantly shifted from those expected for resonance excitation of a conventional SPP on a pure silver surface

“…17,18 Dipole antennas have been demonstrated to enhance the optical cross sections of Ge nanophotodetectors. 19 Of particular practical interest is the use of a plasmonic bull's eye structure (BES), that is, a concentric plasmonic grating surrounding a nanohole aperture, 20,21 as such a structure can capture light from a large area and concentrate it into a nanoscale aperture. Extraordinary optical transmission has been demonstrated in these structures as a result of the efficient coupling of incident photons into surface plasmon polaritons, which are guided towards the center of the BES and constructively interfere in the aperture, resulting in high transmission efficiencies.…”

High-sensitivity photodetection is at the heart of many optoelectronic applications, including spectroscopy, imaging, surveillance, remote sensing and medical diagnostics. Achieving the highest possible sensitivity for a given photodetector technology requires the development of ultra-small-footprint detectors, as the noise sources scale with the area of the detector. This must be accomplished while sacrificing neither the optically active area of the detector nor its responsivity. Currently, such designs are based on diffraction-limited approaches using optical lenses. Here, we employ a plasmonic flat-lens bull's eye structure (BES) to concentrate and focus light into a nanoscale colloidal quantum dot (CQD) photodetector. The plasmonic lenses function as nanofocusing resonant structures that simultaneously offer color selectivity and enhanced sensitivity. Herein, we demonstrate the first CQD photodetector with a nanoscale footprint, the optically active area of which is determined by the BES; this detector represents an exciting opportunity for high-sensitivity sensing.

“…A resonant interaction leads to an enhanced transmission at wavelengths determined by the corrugation period [3][4][5][6][7][8]. It is also possible to confine the transmitted beam with the use of the periodically corrugated metal surface with subwavelength apertures [9 -12].…”

“…In recent years, the rapid development of MEMS technology allowed challenging radically the performances of particular variable phase shifters in terms of insertion loss, drive power, monolithic integration, and cost. Examples of demonstrated MEMS-based variable phase shifters are the distributed MEMS transmission line (DMTL) [5] and the reflection-type phase shifter [6], which exhibit true-time and constant-phase delays, respectively.…”

We studied the grating-coupling phenomena between surface plasmons and electromagnetic waves in the microwave spectrum. We first present the experimental and theoretical results of an enhanced microwave transmission though a subwavelength circular annular aperture with and without metallic gratings. We demonstrate that a 145-fold enhancement factor could be obtained with a subwavelength circular annular aperture that was surrounded by periodic metallic gratings. This was assisted by the guided mode of the coaxial waveguide and by coupling to the surface plasmons. We present the angular transmission distributions from circular annular apertures, and circular annular apertures surrounded by concentric periodic grooves. At the surface mode resonance frequency, the transmitted electromagnetic waves from the subwavelength circular annular aperture surrounded by concentric periodic grooves have a strong angular confinement with an angular divergence of ±3°. We demonstrate that only the output surface is responsible for the beaming effect. Furthermore, we present the field distributions and showed that there is no beaming effect at the off-resonance frequency. © 2006 Wiley Periodicals, Inc
