Applied Physics Seminar
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.
