Abstract

Dichroism and nonreciprocal transmission are crucial in the propagation and modulation of electromagnetic waves. In this work, we investigate the dichroism of Weyl semimetal film in the Faraday and Voigt configurations and the nonreciprocal transmission in one-dimensional photonic crystals containing Weyl semimetals by means of transfer matrix methods. The results show that the circular dichroism and linear dichroism in the Weyl semimetal film both exceed 98%, and they are both multi-channel or broadband. Furthermore, the broadband nonreciprocal transmission of circularly polarized and linearly polarized light in the mid-infrared range are realized in two kinds of one-dimensional photonic crystals containing Weyl semimetals in the Faraday and Voigt configurations. The corresponding bandwidths exceed 20 THz and 10 THz, respectively. At the same time, the isolations in the Faraday and Voigt configurations are more than 45 and 35 dB, respectively. The insertion losses for both are less than 2.0 dB. These results provide a new possibility to design nonreciprocal devices with high isolation, high integration, and wide bandwidth.
