Abstract

We design cylindrical multilayer structures characterized by anisotropy and topological features. This provides a new approach to tailor electromagnetic felds into desired patterns with orbital angular momentum in cylindrical geometries as ring resonators and fbers. We use transformation optics to deal with anisotropic circular structures, and rigorously defne the edge states. The resulting topologically protected high-localized modes, at the core/cladding interface, with angular momentum may trigger the developments of new disorder-robust devices and high Q-microcavities for applications in light transmission, quantum technology, nonlinear optics, TeraHertz devices, and biophysical sensors.
