Applied Physics Seminar
Patrick Uebel was born on May 20th, 1984 in Nuremberg. He started studying Physics in 2004 at the University of Erlangen-Nuremberg where he received his Diploma in 2009. He did his thesis at the Max Planck Institute for the Science of Light in the group of Prof. Philip Russell on Excitation of long-range spiralling surface plasmon polaritons. During his studies he received a scholarship to spend half a year at the University of York, UK. He continued to work in Prof. Russells group as a PhD student. His current research interest are plasmonic and bulk optical properties of metals integrated in optical fibers.
In this talk I give a short introduction to fiber optics, including modal propagation in step-index-fibers, PCF and plasmonic nanowire waveguides. I discuss the fabrication of metal-filled optical fibers and review the basic theory of surface plasmon polaritons coupled to dielectric waveguides. I present our most recent experimental results, including
Generation of octave-spanning, azimuthal polarized supercontinuum (P. Uebel et al. New J. Phys. 2011 (13), 063016, video abstract online) Polarization-resolved near-field mapping using SNOM of a coupled plasmonic waveguide array (P. Uebel et al. CLEO US 2012, CF2M.2) Gold nanotips as plasmonic hot spot generators Plasmonic hybridization of nanowire waveguides (H. Lee et al. Opt. Lett. 2012, submitted)
In particular, I will focus on the SNOM experiment which was done using a customized device from WITec ALPHA300 S.
