Abstract

This paper proposes a metallic hole array of a rectangular converging-diverging channel (RCDC) shape with extraordinary transmission. We use a three-dimensional (3D) finite element method to analyze the transmission characteristics of two-dimensional metallic hole arrays (2D-MHA) with RCDC. For a straight channel MHA, when the aperture size is reduced, the transmission peaks have a blue-shift. The same result is observed for a smaller gap throat for the RCDC structure. For the rectangular holes with a high length-width ratio, a similar blue-shift in the transmission peaks as well as a narrower full width at half maximum (FWHM) are observed. The asymmetry from the rectangular shape gives this structure high selectivity for light with different polarizations. Furthermore, the RCDC shape gives extra degrees of geometrical variables to 2D-MHA for tuning the location of the transmission peak and the FWHM. The tunable transmission property of this structure shows promise for applications in tunable filters, photonic circuits, and biosensors.

Side view of the structure. The thickness of the film is t, and there is a rectangular RCDC hole array with a converging angle θ in it.

Fig. 2.
Fig. 2.

Top surface of the structure. The rectangular hole array is periodic in both the x and y directions, and the periodicity for the two directions are the same (22μm). The inset shows the top view of a single rectangular hole, with a and b defined as the long and short sides. The lengths of the two sides are not identical, resulting in an asymmetric structure along the x and y directions.

Transmittance spectrum with the same hole area and converging angle θ=30°, but different a/b ratios (a) a=16μm, b=12μm, (b) a=18μm, b=10.7μm, and (c) a=20μm, b=9.6μm. The solid and dashed lines represent the transmissions for different polarizations. The vertical dashed lines denote the wavelength of each peak.

Transmissions for different converging angles. The hole area, film thickness and a/b ratio (16μm/12μm) remain the same in all cases.

Transmissions for different metal film thickness. The hole area, converging angle (30°) and a/b ratio remain the same in all cases. The solid and dashed lines represent the transmissions for different polarizations.
