Twisted topological photonic crystal fiber
Abstract
Topological states promise protection against disorder and scattering for transmitted signals, but no topological state has previously been realized in a scalable communications platform. In this project, we will design optical fiber with a photonic crystal cross-section in which signals are topologically protected. This design is based on a twisted fiber with a honeycomb-lattice cross-section and exploits analogies with the behavior of electrons in a graphene sheet. A unique feature of this architecture is the design of topologically protected modes of arbitrary shape. The application of topological design principles to fiber promises to enhance the transmission of quantum information over kilometer scales.
