At the Chair for Ultrafast Nanooptics in the Physics Institute of Bayreuth University, Germany, we currently have two open positions suitable for PhD or PostDoc projects. The group focuses on plasmonics and nanooptics and combines ultrafast and nonlinear spectroscopy with all kinds of emitters, at room temperature and low temperature. For details check our website at http://www.ep3.uni-bayreuth.de .
Plasmonic nanostructures locally increase the electric field and are also themselves highly optically nonlinear, so that processes such as the generation of the second (SHG) or third harmonic (THG) are very efficient. The interaction of fundamental field distribution, plasmonic resonance, nonlinear polarization and finally nonlinear emission is quite complex. In special cases, this can be observed despite the limited resolution of a far-field microscope (D. Wolf et al., Nat.Comm 2016). Within the framework of a DFG project, however, we are looking for structures that enable well-controlled plasmonic near-fields, for example, in order to excite molecules at specific positions on the nanometer scale. Therefore, we want to image non-linear plasmonic near-fields in a near-field microscope consisting essentially of a scattering AFM tip as a probe. In an iterative process of simulation, production and measurement, a structured light source is to be developed that works below the diffraction limit.
