Strong Rotational Anisotropies Affect Nonlinear Chiral Metamaterials

David C Hooper et al. Adv Mater. 2017 Apr.

Abstract

Masked by rotational anisotropies, xthe nonlinear chiroptical response of a metamaterial is initially completely inaccessible. Upon rotating the sample the chiral information emerges. These results highlight the need for a general method to extract the true chiral contributions to the nonlinear optical signal, which would be hugely valuable in the present context of increasingly complex chiral meta/nanomaterials.

Keywords: chiral media; metamaterials; nanomaterials; nonlinear optics.
