摘　　要：应用4×4传输矩阵法数值分析线偏振光在一维磁光光子晶体中的传输特性.首先推导了4×4传输矩阵,然后数值计算线偏振光在一维磁光光子晶体中传输时的透射谱和法拉第旋转角,结果表明:当施加外磁场时,由于磁光材料的磁光效应,线偏振光中的左旋圆偏振光和右旋圆偏振光在一维磁光光子晶体中传播时的透射谱不再重合,导致透射谱发生分裂.最后计算透射光的电场强度x分量和y分量的振幅和相位,得到透射光的表达式和法拉第旋转角.The transmission characteristics of linearly polarized light in one-dimensional magneto-optical photonic crystals are numerically analyzed by using the transmission matrix method. The 4×4 transmission matrix was derived, and then the transmission spectrum and Faraday rotation angle of linearly polarized light in one-dimensional magneto-optic photonic crystal are calculated numerically. The results show that the transmission spectra of left-handed and right-handed circularly polarized light propagating in onedimensional magneto-optic photonic crystals do not coincide with each other due to the magneto-optic effect of magneto-optic materials when an external magnetic field is applied. Finally, the amplitudes and phases of the x-component and y-component of the electric field intensity of the transmitted light are calculated, the expression of the transmitted light is obtained, and the Faraday rotation angle is calculated.
