Nano-Optics with Structured Light – A Tale of Photonic Wheels, Nanoscopic Lighthouses and Polarization Möbius Strips

Date Mo, 15.04.2019 - Mo, 15.04.2019
Time 16:45h
Speaker Prof. Dr. Peter Banzer
Location ETHZ, Hönggerberg Campus, HPF G-6
Program Strong spatial confinement of polarized light results in the formation of complex electromagnetic field landscapes, which can be tailored at the nanoscale. From an applied and a fundamental perspective, suchfield distributions with sub-wavelength features constitute an intriguingplayground. Tailored and spatially structured light fields at the nanoscale pave the way for an incredibly wide range of applications in the fields of super-resolution imaging and microscopy, nano-optics, plasmonics, quantum optics, material processingand many more. In addition, highly confined electromagnetic field distributions may also feature fascinating novel properties hidden in the complex field structure.In this talk, we start with a short introduction to structured light at the nanoscale. In the main part of the presentation, a small selection of research activities of the group will be discussed. For instance, we plan to introduce the intriguingand still pretty young research area of transverse angular momentaof light,also known asphotonic wheels. We will show an interesting application of this phenomenon in nanoscale light-matter interaction, i.e., the directional coupling and routing of light as well as the localization of nanoparticles utilizing the concept of nanoscopic lighthouses. Last but not least, we will present an experimental method for measuring the three-dimensional field including spatial maps of the amplitude and phase distributions of individual field components with deep sub-wavelength resolution.This tool enables us to study experimentally highly confined electromagnetic fields and novel phenomena hidden therein. As an example, the topological structure of light will be discussed, with an emphasis on polarization Möbius strips.
