Figure 2. Simulated optical response of chiral metamaterial.

Figure 2

(a,b) Simulated optical absorption spectra under LCP (blue) and RCP (red) illumination for LH (a) and RH (b) metamaterials. (c) Circular dichroism spectra for both the LH (blue) and RH (red) metamaterial. (d) CD as a function of resonator size. Dimensions of the structures (I–V) are follows: L1=115, 125, 130, 150 and 160 nm; L2=95, 105, 120, 130 and 140 nm; W1=110, 115, 120, 120 and 140 nm; W2=85, 85, 90, 90 and 100 nm; P1=305, 335, 370, 410 and 440 nm; P2=230, 235, 240, 240 and 260 nm, respectively. The other dimensions are the same as Fig. 1a. (e,f) For the LH metamaterial, the reflected LPL components, Ex (red) and Ey (blue), on multiple reflections for LCP (e) and RCP (f) light at wavelength of 1,350 nm. (g,h) Simulated electric (g) and magnetic (h) fields for LCP and RCP illumination at wavelength of 1,350 nm.
