Integrated magneto-plasmonics for non-reciprocal optical devices – Presented by Béatrice Dagens, Centre for Nanoscience and Nanotechnology

Integrated magneto-plasmonics for non-reciprocal optical devices – Presented by Béatrice Dagens, Centre for Nanoscience and Nanotechnology at the 19th edition European Conference on Integrated Optics, which takes place on 3 – 5 April 2017 at Eindhoven University of Technology, Blauwe Zaal in Eindhoven, The Netherlands.

Non-reciprocal transmission in optical systems could considerably enrich possible architectures of integrated photonic circuits by enabling isolator or circulator functions to be exploited. During the last decade numerous guided structures have been proposed using transverse magneto-optical Kerr effect (TMOKE), with still excess footprint or insertion loss. Since surface plasmon polaritons can strongly enhance light-matter interaction, magneto-plasmonics is one way to improve isolator performance. We propose here a new device principle supported by recent numerical results on TMOKE based non-reciprocal transmission involving a bismuth iron garnet waveguide coupled to a gold grating on its top.

About Béatrice Dagens
Béatrice Dagens received the PhD degree in 1995 on high-power semiconductor optical amplifiers. Within Alcatel Company from 1996 to 2007, her activity was focused on SOA based devices, quantum dash laser diodes and ferromagnetic integrated optical isolators. Since end 2007, she has been CNRS Senior Researcher, presently at the Centre for Nanoscience and Nanotechnology (C2N). Her current research includes magneto-photonic, plasmonic and magneto-plasmonic nanostructured components for compact integrated photonic devices.

About Centre for Nanoscience and Nanotechnology
established on June 1st 2016, the Center for Nanoscience and Nanotechnology (C2N) results from the merger of the former Laboratory for Photonics and Nanostructures and Institut d’Electronique Fondamentale. The newly created C2N develops basic and applied research in the field of material science, nanophotonics, nanoelectronics, nanobiotechnologies, microsystems, and nanotechnologies.
