Professionally, I am a Physicist (Dipl.-Phys.), currently working for three months as a visiting scientist in the Atwater labs at the California Institute of Technology, Pasadena.
My home institute is the Max Planck Institute for the Science of Ligh (MPL) in Erlangen.
I am working on my Ph.D. in the research group of Prof. Peschel, which is part of Division Leuchs of the MPL.
Previously I have studied physics and a bit of philosophy at the University of Erlangen and the University of York. I finished my studies with an experimental thesis on “Oblique-incidence excitation of surface plasmon polaritons on small metal wires” (arXiv:0906.2089v1) in the group of Prof Russell at the Max Planck Research Group of Optics, Information and Photonics, the predecessor of the newly founded Max Planck Institute in Erlangen.
Nanoplasmonics
My field of interest is the physics of very small structures (~50-100 nm a ten-thousandth of a hair diameter) in which it is possible to confine and guide light. As light in those structures can be described as so called propagating plasmons, more precise, surface-plasmon-polaritons (w), the field of research is called “plasmonics”, referring to the size scale “nanoplasmonics”. My field of research can be subsumed under the larger field of “nanosciences”.
More precisely, I am in my projects working on fundamental research, investigating the basic building blocks of nanoplasmonic “optical” circuitry with a special focus on subwavelength plasmonic (SPP) waveguides, directional couplers, discrete diffraction and negative diffraction in planar plasmonic systems. Up to now I have, together with my colleagues, realized efficient antennas for transferring light from a free beam into those structures. We were also able to demonstrate and fabrucate nanostrcutures which offer coupling between nanoplasmonic waveguides on the shortest lengths, achieved up to now.
