Asymmetric light reflection at the reflecting layer incorporated in a linear, time-independent and non-magnetic two-dimensional photonic crystal

Abstract

For the first time, we show the phenomenon of asymmetric light reflection at the reflecting layer incorporated in a linear, time-independent and non-magnetic two-dimensional (2D) photonic crystal (PC). The proposed reflector shows asymmetry in the reflection (and hence, in transmission), if incident and reflected ports are interchanged. The possibility shown here should be of interest from the point of view of basic optics and should have interesting consequences/applications in applied optics.
