Group Seminar via Zoom: Metamaterials and Topology-Enabled Light-Matter Interactions
Mikhael Shalaev, Duke University
group meeting via Videoconference (Zoom)
Tuesday, April 21st, 14:00 (MEZ)
Dealing with the unique situation of partial lock downs worldwide and home office solutions at our Institute due to the current spreading of the Covid 19 virus, we are now holding our group seminars and journal clubs via video conference.
This procedure enables us to continue our research, enhance discussions and exchange important information.
Rapid development of nano-fabrication techniques in recent years enabled the possibility to create structures on the nanometer scale with dimensions comparable and even much smaller than light wavelength. These structures allow to control and manipulate light propagation and may find application for optical highly efficient communication systems. In this talk I will consider three kinds of photonic structures. First, I will talk about topological photonic crystals for robust and scattering-free light propagation. Second, I will discuss dielectric silicon-based metasurfaces for efficient control on light propagation in transmission mode at telecommunication frequencies. Finally, I will cover theoretical description of second harmonic light generation in optical metamaterials with vortex beams.
