The lecture course entitled "Nanoplasmonics" will give an introduction to the research field of metal-based nanophotonic system. “The promise of plasmonics” (Harry A. Atwater, Scientific American 2007) is to overcome the well-known diffraction limit of light which limits feature sizes of photonic components to λ/2n (λ: speed of light, n: refractive index). For this purpose, researchers study and exploit novel excitations at the interface between a metal and a dielectric, so-called surface plasmon polaritons, allowing sub-wavelength confinement of light at this interface. This strong confinement is naturally accompanied by the massive enhancement of the electromagnetic field strength and, thus, paving the way to strong light-matter-interactions, non-linear optical effects and ultra-sensitive single molecule studies. Nanoplasmonic concepts and devices are already well established and find many applications in such diverse research fields as e.g. bio-sensing, novel light sources, non-linear frequency conversion, efficient photovoltaics, and even quantum information technology.
We will start the course by discussing the mathematics of surface plasmon at metal-dielectric interfaces which are mainly governed by basic electrodynamics. After the fundamentals, we will presented a number of concepts for generating and detecting surface plasmon polaritons in various different geometries and discuss the corresponding experimental techniques. Afterwards we will discuss in detail two different kinds of surface plasmons, namely (i) propagating surface plasmon polaritons in waveguide structures and (ii) localized surface plasmon polaritons in nanoparticles. In the remainder of the course we will touch amongst others topics like non-linear plasmonics, meta-surfaces and -materials, plasmon-enhanced nano-focusing and enhanced-resolution microscopy, quantum plasmonics, surface plasmon lasers and graphene-plasmonics.
Besides the fundamental nano-plasmonic concepts and their application in novel devices we will also deliver insights in our current plasmonics research at WSI and ZNN and provide the possibility to visit our labs and discuss our research with PhD students.
For students interested in this course we recommend a basic knowledge of solid-state physics, electrodynamics, basic optics and quantum mechanics!
