Online-Seminar: Plasmonic Devices Fabricated by Two-Photon Polymerization and Microscope Projection Photolithography

Plasmonics is a rapidly developing field that takes advantage of the coupling of light to electric charges in metals at a dielectric–metal interface. This allows for the localization of light into subwavelength dimensions, enabling strong field confinement and enhancement. This feature is promising to meet the demands for progressive miniaturization and compact integration of more complex optical devices and networks. With respect to the realization of plasmonic devices, direct laser writing by two-photon polymerization (2PP) is one of the most promising approaches for fabrication of high-resolution 3D micro- and nanostructures. Microscope projection photolithography (MPP) which enables rapid and flexible structuring is powerful in high-resolution 2D manufacturing. In this presentation, various 2D and 3D plasmonic devices created by 2PP and MPP are presented. Their properties were characterized using leakage radiation microscopy, in particular excitation and visualization of surface plasmon polaritons (SPPs) was demonstrated. Such plasmonic manipulation effects are promising elements for the development of novel nanophotonic and plasmonic devices, e. g. optical sensors, waveguides and optical trapping devices at the nanoscale.
