Abstract: Circular polarization discrimination is desired for use in many optoelectronic applications. By integrating asymmetric metamaterials with active materials, circular‐polarization‐discriminative light–matter interaction can be realized. Nevertheless, the circular polarization extinction ratio for absorption of the active…

Abstract: Abstract In this paper, we theoretically studied that the high extinction ratio polarizers can be designed with hexagonal boron nitride (hBN). We demonstrated that the transverse electric wave can pass the single hBN slab with…
