Plasmonic nanostructures are metallic structures with dimensions in the sub-100 nm range, which exhibit extremely strong optical effects. In this talk, I will illustrate some of the nanotechnologies that we use to produce these structures – from electron beam to lithography with EUV interference lithography using the Swiss Light Source – and some of their applications to control light at the nanoscale.

Bio

Olivier J.F. Martin is Professor of Nanophotonics and Optical Signal Processing at the Swiss Federal Institute of Technology, Lausanne (EPFL), where he is currently head of the Nanophotonics and Metrology Laboratory and Director of the Doctoral Program in Photonics. His research interests focus on the interactions of electromagnetic fields with low dimension systems, especially in the optical regime. Plasmonics is at the heart of his current research interest, with applications in optical signal processing, plasmonic antennas and biosensing. Dr. Martin has authored over 200 journal articles and holds a handful of patents and invention disclosures. He has received the 1999 Latsis University prize for contributions to the study of near-field optics and photonic bandgap structures.
