Chiral and Nonlinear Metamaterials: Properties, Fabrication, and Applications I
11:30 Invited talk : Nonlinear processes in plasmonic metamaterials
A. D. Barbosa Neira, G. Marini, S. Peruh, A. Krasavin, N. Olivier, M. Nasir, W. Dickson, G. A. Wurtz, Anatoly Zayats
King's College London (United Kingdom) Experimental studies and numerical modeling of nonlinear optical processes in plasmonic metamaterials based on assemblies of metallic nanorods will be presented. Second- and third-order nonlinear optical response originating from a plasmonic component of the metamaterial will be discussed. Nanorod-based plasmonic metamaterials can be used for engineering strongly enhanced nonlinear optical properties with the required spectral and temporal response.
11:50 Invited talk : Optical characterization of self-assembled chiral meta and nano surfaces by nonlinear second harmonic generation.
Marco Centini, Alessandro Belardini, Alessio Benedetti, Mario Bertolotti, Concita Sibilia
Universita di Roma La Sapienza (Italy) We report an overview of second harmonic generation measurements showing nonlinear circular dichroism raised by self-assembled nanopatterned surfaces of different morphologies and material components. Straight metallic wires, curved metallic wires, partially metallized spheres and carpets of tilted nanorods have been characterized to investigate the importance of the geometry obtained by different experimental fabrication techniques and to establish the criteria for optimized circular dichroism.
