Abstract

We introduce resonant absorbers that consist of linear metal wires embedded inside of a titanium dioxide grating. We show that in these structures the guided-mode resonance may lead to the almost total absorption of one polarization component and greatly enhance the absorption in localized surface plasma resonance. In addition, we show that the structures have potential to function as filters or polarizing beamsplitters. Absorption of 99.67 % has been obtained together with the contrast of 6600 at the wavelength of 532 nm. This corresponds the extinction of 8.8597. The results have been verified experimentally by fabricating an absorbing filter with electron beam lithography and atomic layer deposition technique. The absorption is remarkably high considering the thickness of the structures which is only 219–333 nm.

Absorbing grating geometry. Metal inside TiO2 is either gold or aluminum. The period of the grating is d, the line width is l, the width and the height of the metal wire are D1, and D2, respectively, the height of the bottom TiO2 layer is h1, the height of the TiO2 line is h2, and the distance between metal wire from the top of the grating is h3. The parallel (||) polarization indicates light with the electric field in the direction of the y-axis. The perpendicular (⊥) polarization indicates light with the electric field in the direction of the x-axis.

Electric field intensities and the Poynting vector distributions for the absorbed components inside one grating period for the designs A (a) and B (b). Light is incident along the z-axis. In (a) the incident light is polarized perpendicularly to the grating lines. In (b) the incident field is polarized parallel to the grating lines. The material on the top of and on the sidewalls of aluminum is aluminum dioxide. The scale is logarithmic.
