Running around a Gyrotropic Material

Abstract:

Non-reciprocal component is very important for nanophotonic circuit. In this article, we demonstrate that a kind of unidirectional surface state can exist in various interfaces between magnetized gyrotropic material and other medium. Since this type of modes is not limited by bandgap as those in photonic crystals, it provides possibilities for making broad-spectrum non-reciprocal devices.
