Photonic topological edge states in metallic and alldielectric structures

Abstract

Topological properties play a fundamental role in many physical phenomena. One of the examples from condensed matter physics is the recently discovered, novel, nontrivial phase of matter called topological insulators. Alternatively, photonics offer a unique platform for emulation of condensed matter systems in a simple and controllable way. Recently, there has been a burst of interest in exploring topological orders with photons, with the discovery of a new class of nontrivial states in photonic topological insulators. Here, we present our recent experimental and numerical results devoted to the observation of photonic topological edge states in electromagnetic structures. Show more
