Absorption Circular Dichroism Induced by Contorted Electrical Oscillations in Rectangular Nanoholes

Abstract The chiroptical response of plasmonic chiral nanostructures can be tuned by combining different structures. In this paper, an L-shaped metal strip is introduced into a rectangular metal nanohole to generate absorption circular dichroism (ACD). The results of a finite-element method calculation show that ACD effects result from contorted electrical oscillations in the L-shaped strip. Additional calculations show that the ACD effects of the proposed metasurface depend strongly on the structure parameters. These findings provide not only a mechanism for enhancing chiroptical responses in planar structures but also a general strategy for the chiral manipulation of light and creation of chiroptical devices..
