Abstract
Tuning the optical response of metasurfaces can unleash their full potential as compact and reactive optical elements. Here, we present two different approaches to tune the spectral response of a metasurface. In the first approach, a micro-electromechanical system(MEMS)-actuated metasurface is demonstrated in the visible range of the optical spectrum. It consists of an amorphous silicon nanopillar array and a suspended silicon membrane with integrated electrostatic actuators. The second approach utilizes light itself to reconfigure the metasurface by trapping nanoparticles within a templated plasmonic substrate. Optical forces control the position of the nanoparticles, which in turn tune the metasurface spectral response.

Olivier J.F. Martin studied physics at the Swiss Federal Institute of Technology Lausanne (EPFL) and conducted his PhD at IBM Zurich Research Laboratory, where he studied semiconductor lasers. After a stay at the UC San Diego, he became Assistant Professor at the Swiss Federal Institute of Technology Zurich (ETHZ). In 2003 he was appointed at the EPFL, where he is currently Full Professor of Nanophotonics and Optical Signal Processing. Dr. Martin conducts a comprehensive research that combines the development of numerical techniques for the solution of Maxwell’s equations with advanced nanofabrication and experiments on plasmonic systems. Applications of his research include optical antennas, metasurfaces, nonlinear optics, optical nano-manipulations, heterogeneous catalysis, security features and optical forces at the nanoscale. Dr. Martin has authored over 300 journal articles and holds several patents and invention disclosures.
