Abstract

Coupled split-ring-resonator metamaterials have previously been shown to exhibit large coupling effects, which are a prerequisite for obtaining large effective optical activity. By a suitable lateral arrangement of these building blocks, we completely eliminate linear birefringence and obtain pure optical activity and connected circular optical dichroism. Experiments around a 100THz frequency and corresponding modeling are in good agreement. Rotation angles of about 30° for 205nm sample thickness are derived.

(a) Illustration of our metamaterial’s chiral unit cell composed of gold SRRs. The lateral dimensions of the SRRs are indicated on the left-hand side. (b) Electron micrographs of a typical fabricated structure. The normal-incidence image illustrates the high alignment accuracy of the two stacked layers. Inset, oblique view onto the sample. The scale bars are 400 nm .

Calculated optical properties. (a) Normal-incidence transmittance spectra that can be directly compared with the experiment shown in Fig. 2. The intensity conversion (not shown) is below 10 5 for the entire spectral range. (b) Calculated rotation angle φ and tangent e of the ellipticity angle of the transmitted light for linearly polarized incident light. (c) Difference of refractive indices Δ n = n RCP n LCP retrieved from the complex transmittance and reflectance spectra.

False-color plots of the axial component of the local magnetic field in two planes cutting through the SRR layers for (a) LCP incidence at 3.2 μ m wavelength and (b) for RCP incidence at 2.5 μ m . Schemes of the corresponding underlying electric currents within the SRR are shown in (c) and (d), respectively.
