Abstract

Acousto-magneto-plasmonics deals with experimental and theoretical investigations of interactions between the acoustic, magnetic and plasmonic transients in hybrid metal ferromagnet multilayer structures excited by ultra-short laser pulses. The main focus is on understanding the novel aspects of acoustic dynamics in materials as well as the peculiarities in the nonlinear optical and magneto-optical response in nano-scaled structures. For example, the nonlinear optical detection is illustrated in details by probing the static magneto-optical second harmonic generation in gold-cobalt-silver tri-layer structures in Kretschmann geometry. Furthermore, we show experimentally how the nonlinear reshaping of giant ultra-short acoustic pulses propagating in gold can be quantified by timeresolved plasmonic interferometry and how these ultrashort optical pulses dynamically modulate the optical nonlinearities. An effective medium approximation for the optical properties of hybrid multilayers enables the understanding of novel optical detection techniques. Exploring acousto-magneto-plasmonic functionalities at the nano-scale provide the experimental platform for designing the next-generation ultrafast nano photonic devices. As the next step, functionalizing hybrid metalferromagnet multilayer structures with solid-state nanoscale light emitters will allow for detailed quantumoptical studies of magneto-plasmonic interactions at the nano-scale using nonlinear optical and quantumoptical techniques. From an even more fundamental perspective, combining graphene-based plasmonic nanostructures with optical metamaterials may shade light on the mysteries of topological plasmonics.

Biography

Vasily Temnov has obtained his PhD from University Duisburg-Essen in 2004. After Post-doctoral studies at Dortmund Technical University and Massachusetts Institute of Technology, he became a CNRS Researcher at Institute des Molécules et Matériaux du Mans in Le Mans in 2011, where he also obtained a Habilitation degree in 2012. Being the recipient of numerous academic awards by the CNRS, DAAD and the Humboldt Foundation, he served as a Coordinator of an international network on the nonlinear nano photonics “NNN-Telecom” as well as several French-German ANR-DFG and French-Russian CNRS-RFBR collaborative research projects.
