Title: Metamaterials and Topology-Enabled Light-Matter Interactions
Abstract: 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-freelight 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.
