摘要
Abstract In this paper, we propose a bulk Dirac semimetals (BDSs) metamaterial to realize quasi-bound state in the continuum (quasi-BIC) based optical modulator. When perturbation is introduced into the system by breaking symmetry, the BIC will transform into quasi-BIC with high quality ( Q ) factor and radiation loss can be effectively controlled. What’s even more interesting is that the transmission of the quasi-BIC can be modulated by varying the Fermi energy of BDSs while the resonance frequency almost unchanged, the maximum transmission difference is up to 82% indicating that the proposed BDSs metamaterial shows good performance as an optical modulator.
