“…An experimental signature for the Fabry-Perot resonances is that they do not respond to angle-tuning, which does influence the surfacewaves coupled to a periodic hole-array. As a result, the angle-tuned dispersion shows a flat-band response, which has been demonstrated for square-hole arrays in the infrared using copper meshes [78], as shown in Fig. 7.…”

Extraordinary optical transmission through an array of holes in a metal film was reported by Ebbesen and coworkers in 1998. Since that work there has been abundant research activity aimed at understanding the physics and at the development of the many applications associated with this phenomenon, hence the topic of this review. The study of hole-arrays in a metal is not new -theoretical contributions on a small-hole array date back to Lord Rayleigh's description of Wood's anomaly in 1907 and there has been considerable research on metal meshes and holearrays since 1962. Bethe's theory, adapted to treat hole-arrays, is the simplest theoretical description of the transmission resonance. Following a description of this basic theory, we present the research on the additional effects from variations in real metal properties at different wavelengths, film thickness, holeshape and lattice configuration. The many promising applications being developed using hole-arrays are examined, including polarization control, filtering, switching, nonlinear optics, surface plasmon resonance sensing, surface-enhanced fluorescence, surface-enhanced Raman scattering, absorption spectroscopy, and quantum interactions. Finally, the various approaches, developments in hole-array fabrication, and integration of hole-arrays into devices are described.

“…The electromagnetic wave is confined on the surface and coupled into the hole in the form of SPPs, giving rise to the transmission peaks [11] . As the matching condition above is a rigorous equation the resonant peak is usually rather distinct, which can be seen in Fig.…”

This paper illustrates the fundamental transmission characteristics of periodic air hole metal array utilizing FDTD simulations. A metal-dielectric structure with periodic hole arrays perforated in the metal layer is presented. By changing the values of parameters, such as dielectric constant, thickness of the metal film and hole periodicity, the transmission responses are explored at terahertz regime. The surface plasmon polaritons play a significant role in the transmission.Based on the analysis, a wide band-pass filter containing metal-dielectric-metal layers is designed with square lattices of air holes in metal layers. The parameters of the structures are carefully selected to give a filtering characteristic with relatively wide and flat pass-band exceeding 200 GHz, over 95% THz transmittance and easy manufacture process. This kind of sample structure can be the potential candidate of filters in terahertz systems.

“…The work that has been done in the mid-IR has already demonstrated quite promising results. Meshes and periodic structures utilizing SPs and designed for the mid-IR have been shown to have similar properties to structures in the visible [9][10][11]. In addition, it has also been shown that chemical attachment to the mesh surface can enhance the sensitivity of molecular absorption measurements by several orders of magnitude [10].…”

We demonstrate active control of propagating surface waves on a mid-infrared extraordinary optical transmission grating. The surface waves are excited at the interface between a GaAs substrate and a periodically patterned metal film using a dual wavelength quantum cascade laser. The spectral properties of the laser and the transmission grating are characterized by Fourier Transform Infrared spectroscopy. In addition, the far-field emission from excited surface waves at the metal/GaAs interface is studied using a novel spatial and spectral imaging technique. By actively controlling the optical properties of the grating, we demonstrate the ability to control the coupling of incident coherent radiation to surface waves on the grating. With increased tunability of the grating, directional control of excited surface waves should be achievable. These results suggest that the development of actively tunable plasmonic structures could result in plasmonic routers and switches for interconnect or sensing applications.
