Effect of hole diameter on terahertz surface-wave excitation in metal-hole arrays

The effect of the hole diameter on the surface wave ͑SW͒ excited on the metal surface perforated periodically with circular holes has been investigated in the terahertz ͑THz͒ region. We find that the SW is localized more strongly on the metal surface with increasing the hole diameter. These results provide the evidence for the existence of the SW-like mode, having properties similar to the surface plasmon polariton in the visible region, even in the THz or lower frequency regions, where metals are regarded as the nearly perfect conductor.The resonant light transmission phenomenon for metalhole arrays is attracting much attention with regard to underlying physics 1-5 and the development of potential applications. [6][7][8] The transmittance of the metal-hole array is several times higher than that expected from the hole aperture fraction. The mechanism of such an anomalous transmission characteristic is nowadays widely understood in terms of the excitation of the surface waves ͑SWs͒ 2-5,9 on the periodically structured metal surface and Fano-like interference between the SW and directly transmitted electromagnetic wave. 4 Here, we should empasize that in the 1960s similar resonant transmission characteristics of metal meshes were reported in the millimeter wave or far infrared regimes, 10-12 and the contribution of SWs, called Zenneck waves, was discussed in Ref. 10.The intensity of the SW is attenuated exponentially with distance from the metal-dielectric interface. The attenuation lengths both into the dielectric and metal sides are comparable to or shorter than the wavelength of light in the visible or near infrared regions. In the terahertz ͑THz͒ or lower frequency regions, on the other hand, the attenuation length of the SW into the dielectric side is several orders of magnitude longer than the wavelength for a flat metal surface, while the attenuation length into the metal side is several orders of magnitude shorter than the wavelength. In this case, one cannot recognize such a delocalized electromagnetic wave as the SW. Owing to the existence of the perforated structure, however, the attenuation length of the SW is possibly reduced to the order of the wavelength 13,14 and thus the resonant transmission phenomenon can be observed even in the THz and lower frequency regions. 15 Such SWs ͑called spoof surface plasmon polariton͒ have a possibility to cause a variety of optical characteristics of metal-hole arrays. In our previous study, for example, we observed the interesting transmission characteristics of double-layer metal-hole arrays based on the near-field coupling between the SWs excited on the two metal surfaces. 16 The surface localization property and lifetime of the SW on the metal-hole arrays depend on some geometrical parameters, such as the hole diameter, slab thickness, lattice constant, and permittivity of metals and are important for designing the optical devices made of metal-hole arrays. In this paper, we measured the hole diameter dependence of the surface-wave characteristics on the perfora...

The extraordinary light transmission through double-hole and elliptical nanohole arrays in a thin gold film is investigated for different orientations of the holes relative to the lattice. Even though these bases have similar symmetry characteristics, the polarization follows the orientation of the basis for the ellipse but remains fixed along a lattice vector for the double holes. Furthermore, the maximum transmitted intensity for linearly polarized light is constant for the ellipse, but decreases for the double holes as they are rotated away from being aligned with the lattice. Finite-difference time-domain simulations agree well with the experimental findings. These experiments show how the basis determines both the coupling into the surface plasmon waves and the evanescent transmission through the nanoholes. Both of these effects need to be considered when designing nanophotonic devices using the extraordinary transmission phenomenon.Light transmission through subwavelength holes can be increased by several orders of magnitude with respect to Bethe's theory 1 when the holes are periodically arranged in a thin metal film. 2 This extraordinary transmission is the result of resonant coupling to surface plasmon (SP) waves at the metal-dielectric interface via the array of holes. 3,4,5,6,7 As with other periodic systems, the optical response of the hole array is determined by both the lattice and the basis. The SP waves are longitudinal, so the polarization is collinear with their direction of propagation. 8 This means that the polarization direction of the incident field selects which resonance of the lattice is excited. Recent works have shown that changing the basis shape from circular holes to elliptical 9,10 and rectangular 11 holes has a strong influence on the polarization and resonance properties; as the aspect ratio is increased, the polarization perpendicular to the broad edge of the hole has enhanced transmission and the resonance peaks shift in wavelength. Those works focused on the situation in which the elongated basis was aligned with the array's lattice vector. As a result, they did not separate the contributions of the basis and the lattice. Furthermore, both the ellipses and the rectangles considered in those works have a strongly polarized (evanescent) transmission mode through the holes, which was not distinguishable from the other polarization effects.In this work, we investigate the effect of the array basis and its orientation on the transmission. By comparing the behavior of ellipses to double-hole arrays, the contributions of the lattice and basis are distinguished. When the ellipses and the double holes are aligned with the lattice, they both show enhanced transmission for light polarized perpendicular to their long axis. Upon rotation of the basis, however, the transmission of the ellipses and double holes have different polarization behaviors. These experimental results are in good agreement with theoretical simulations based on finitedifference time-domain (FDTD) calculations....

Quadrate hole array is explored to study the influence of unsymmetrical periodicity on extraordinary optical transmission through periodic arrays of subwavelength holes. It is found that the transmission efficiency of light and the ratio between transmission efficiencies of horizontal and vertical polarized light can be continuously tuned by rotating the quadrate hole array. We can calculate out the transmission spectra (including the heights and locations of peaks) for any rotation angle θ with a simple theoretical model. PACS number(s):
