Lecture 1: Light Emission in Nanoscale Environments

Time: September 23, 2013, 13:30
Place: IAP seminar room Albert-Einstein-Strasse 15, 07745 Jena

Monitoring of emission of single molecules or nanoparticles has proven to be an important tool for examining and sensing of various biological processes. However, with the advances of the ideas of fluorescent bio-markers it becomes increasingly important to develop techniques for control and detection of single fluorophores detection. This lecture will introduce some of the basic concepts of coupling of emitters to nanoscale structures. In particular, we will focus on the advantages of interaction of fluorophores with plasmonic nanostructures, such as metal nanoparticles and optical antennas. We will then overview some recent advanced concepts of nanoscale manipulation of the intensity, spectrum, lifetime, polarization, and quantum properties of the emitter's radiation.

Lecture 2: Topological Insulators, Graphene and their Applications in Optics

Time: September 26, 2013, 10:30
Place: IAP seminar room Albert-Einstein-Strasse 15, 07745 Jena

The field of topological insulators has emerged as a new important concept in solid state physics. This two part lecture will introduce some of the fundamental principles of topological insulators and will draw on their analogy with the electron transport in graphene structures. We will then review some of the recent ideas where such electronic properties have been applied  in photonics.
