Issue Date: | 2010 | Publisher: | Optical Society of America | Source: | OPTICS EXPRESS, 18(8). p. 8286-8293 | Abstract: | In optics, chirality is typically associated with circularly polarized light. Here we present a novel way to detect the handedness of chiral materials with linearly polarized light. We performed Second Harmonic Generation (SHG) microscopy on G-shaped planar chiral nanostructures made of gold. The SHG response originates in distinctive hotspots, whose arrangement is dependent of the handedness. These results uncover new directions for studying chirality in artificial materials. | Notes: | [Valev, V. K.; Verbiest, T.] Katholieke Univ Leuven, INPAC, B-3001 Louvain, Belgium. [Silhanek, A.
