Real-time and frequency-domain study on plasmonic waveguiding in organic nanofibers published in Phys. Rev. Lett.


Plasmonic waveguides confine and guide light on a subwavelength scale and are considered as high-potential subunits in future integrated opto-electronic devices. In a recent publication in Physical Review Letters, Michael Bauer and his team from the IEAP, together with the group of Horst-Günter Rubahn (Mads-Clausen Institut at the Sydansk Universitet Sonderborg, DK) studied, how waveguiding properties of plasmonic wavguides formed from organic nanofibers can be tuned by morphological modifications. An important aspect of the study was the use of a high-resolution microscopy technique capable of imaging and characterizing individual nanofibers. The work was funded by the German Science Foundation (DFG) through Priority Program 1391 “Ultrafast Nanooptics” and the Danish Council for Independent Research through Research Program “Active Nanoplasmonics (ANAP)”
