Bloch surface waves, a 2D platform for planar optical integration

Date Do, 26.03.2015 - Do, 26.03.2015
Time 11.15
Speaker Dr. Hans Peter Herzig, Optics & Photonics Technology Laboratory (OPT), Swiss Federal Institute of Technology in Lausanne (EPFL), Neuchâtel
Location Universität Bern, Institut für Angewandte Physik, Gebäude exakte Wissenschaften, Hörsaal B116, Sidlerstrasse 5, 3012 Bern
Program A novel platform suitable for fundamental investigations of light propagation through micro- and nano-structures will be discussed. This platform is based on a dielectric multilayer that sustains Bloch surface waves (BSWs). BSWs are electromagnetic surface waves excited at the interface between a truncated periodic dielectric multilayer and a surrounding media. The modification of the top surface to customize a complete 2D micro-system can be produced using e-beam writing, optical lithography or other patterning techniques. The results obtained confirm the possibility of developing a robust multilayer platform that would pave the way for integration of photonic components in photonic chips using standard wafer-scale production.
