Proceedings of SPIE (Metamaterials VII), (ART N° 842311) | Series/Report: | Proceedings of SPIE | Series/Report no.: | 8423 | Abstract: | We report our latest results on second harmonic generation (SHG) microscopy from arrays of G-shaped chiral gold nanostructures. The nanostructures are arranged in unit cells composed of four Gs, each rotated at 90° with respect to its neighbors. As it has already been demonstrated, for linearly polarized light, these unit cells yield a pattern of four SHG hotspots. However, upon increasing the pitch of the nanostructured arrays, extra hotspots can be observed at the edges of the unit cells. While the origin of these extra hotspots remains to be elucidated, their position indicates a relationship to coupling behavior between the unit cells. | Document URI: | http://hdl.handle.net/1942/14707 | ISBN: | 9780819491152 | DOI: | 10.1117/12.921523 | ISI #: | 000305694400017 | Category: | C1 | Type: | Proceedings Paper | Validations: | ecoom 2014 |
