topological edge soliton tagged posts

A novel topological edge soliton developed for nonlinear photorefractive lattices enables robust light beams is promising for photonic technology. Diffraction is a natural property of light beams. It allows light to bend around obstacles. Because light serves as a carrier of information, some of the distorting effects of diffraction must be mitigated for many technological applications. Topological insulators, first unveiled in condensed matter physics, have attracted interest for over a decade. A photonic topological insulator can help ensure consistent propagation of a light beam along its edges...
