“…There is a renewed interest in electromagnetic FP resonances, especially their relevance to the recently observed transmission enhancement through subwavelength openings in normally opaque objects, [1][2][3][4][5][6][7][8] as well as to the ensuing debate on the relative contributions of surface wave versus diffraction in such phenomena. [9][10][11][12][13][14][15][16][17][18][19] It has been shown that light transmission through hole arrays in perfect-conductor thin films, where there can be no true surface waves, may be attributed ͑via Babinet's principle͒ to the reflection by the complementary structure consisting of planar arrays of perfect-conductor disks. 17,18 Transmission can always reach unity at some resonant wavelengths regardless of how small the holes are, while the complementary system can exhibit perfect reflection for arbitrarily small disks.…”

Tuning Fabry-Perot resonances via diffraction evanescent waves

et al. 2007

By studying acoustic and electromagnetic wave transmission through a periodic array of subwavelength holes or slits with various channel lengths, we demonstrate both experimentally and theoretically that diffraction evanescent waves can play an important role in tuning the Fabry-Perot ͑FP͒ resonances. In particular, there can be total transmission peaks at wavelengths much below that of the Rayleigh-Wood limit, and FP resonances can occur for channel length ϳ16% thinner than the half wavelength. In addition, the FP resonance condition can be tuned via both the periodicity and area fraction of holes. As a function of the ratio between the periodicity and plate thickness, the FP resonance is smoothly linked to the surface-wave-like mode induced by the periodic structure factor.

“…[1][2][3][4][5][6] Such nanostructures provide additional functionalities compared to simple circular apertures in terms of very high absolute transmission related to specific waveguided modes in annular apertures, absent in simple circular holes. Coupled to surface plasmon polariton modes on metal film interfaces, these modes provide a possibility to achieve high transmission, field enhancement as well as high extraction efficiency of light trapped in the substrates.…”

“…There have been studies considering AAA with glass as a substrate, in the near-infrared, and the visible regime. [1][2][3][4][5][6] Recently, it was experimentally demonstrated an enhanced transmission around 90%. 9 When glass is used a substrate, it is possible to take advantage of the resonance associated with the cutoff of the TE 11 mode of individual annular apertures.…”

The influence of annular aperture parameters on the optical transmission through arrays of coaxial apertures in a metal film on high refractive index substrates has been investigated experimentally and numerically. It is shown that the transmission resonances are related to plasmonic crystal effects rather than frequency cutoff behavior associated with annular apertures. The role of deviations from ideal aperture shape occurring during the fabrication process has also been studied. Annular aperture arrays are often considered in many applications for achieving high optical transmission through metal films and understanding of nanofabrication tolerances are important.

In-plane illuminated metallic annular aperture array for sensing application

We propose here an application to sensing of annular aperture arrays (AAA). We theoretically investigate the optical properties of the reflective AAA device when illuminated in-plane. The cavity presents almost perfect absorption due to the waveguide mode resonance with strong field localization in the aperture. Additionally, the reflective cavity is modeled to be available for on-chip sensing with a theoretically expected sensitivity of 764 nm∕RIU (refractive index unit , we propose here to investigate the behavior of the electromagnetic field inside coaxial apertures when illuminated in-plane. It appears as a combination of high transmission and planar optics with strong field localization, which should provide a high sensitivity associated to a local interaction with the measured medium. In this Letter, the integration of these nanostructures is considered for embedment in waveguides. Figure 1 presents the schematic view of three periods of the studied structure. It consists of one row of annular holes in a block of gold (Au) embedded on a silicon nitride (Si 3 N 4 ) waveguide. The different parameters are: the periodicity (p), the cut-distance (d 0 ), the inner radius (r i ), the outer radius (r e ) of the circular aperture, and the block metal thickness (d 1 ). The incident medium (Si 3 N 4
