Nonlinear Optical Effects in Hydrogenated Amorphous Silicon Wire Waveguides

Date Mi, 07.03.2012 - Mi, 07.03.2012
Time 10.15
Speaker Edoardo Baldini, Faculty of Engineering, University of Pavia, Italy
Location Universität Bern, Institut für Angewandte Physik, Gebäude exakte Wissenschaften, Hörsaal B78, Sidlerstrasse 5, 3012 Bern
Program Hydrogenated amorphous silicon (a-Si:H) is increasing its role as a promising material for the CMOS-compatible fabrication of optical waveguides in silicon photonics, as it allows more efficient nonlinear interactions than crystalline silicon. We want to investigate the ultrafast optical nonlinear response of a-Si:H wire waveguides using heterodyne pump- probe measurements, evaluating the cross-absorption and the cross-phase modulation and calculating the two-photon absorption figure of merit of the waveguides. Furthermore, we aim at describing the material degradation that can be observed after prolonged exposition of the waveguides to high-power laser radiation.
