【摘要】：为设计厚度薄、层数少且具有良好工作性能的反射型磁光隔离器,在一维单缺陷磁光光子晶体中引入低介电常数超材料.利用传输矩阵法研究该光子晶体的克尔磁光效应,结果表明,采用低介电常数超材料制备层间阻抗差异较大的一维单缺陷磁光光子晶体,既易于在磁光介质层形成较强的局域场,获得接近45°的克尔旋转角,又可增强光的反射,获得较高的能量反射率.本研究为低介电常数超材料应用提供了新的可能.
[Abstract]:In order to design a reflective magneto-optic isolator with thin thickness, few layers and good performance, a low-permittivity supermaterial is introduced into one-dimensional single-defect magneto-optic photonic crystal. The Kerr magneto-optic effect of the photonic crystal is studied by using the transfer matrix method. The results show that one-dimensional single-defect magneto-optic photonic crystals with different interlayer impedance can easily form a strong local field in the magneto-optic dielectric layer, and the Kerr rotation angle of 45 掳can be obtained, and the reflection of light can be enhanced. High energy reflectivity is obtained. This study provides a new possibility for the application of low dielectric constant metamaterials.
