摘　　要：为了获得圆偏振和激光输出一体化的结构,利用增益和损耗微腔、磁性微腔和金属层组成一个复合结构体系,并借助4×4传输矩阵研究该结构的传输特性。结果发现,该结构在一定结构参数范围内产生了较强的法拉第旋转效应,并获得了增益传输模式,实现了多种椭圆偏振或圆偏振激光的同时输出。此外,在某些特定结构参数和特定波长条件下,该结构会产生超强的圆偏振激光。Herein, to obtain an integrated structure of circular polarization and laser output, we design a compound structure composed of gain and loss microcavities, magnetic microcavity, and metal layers. We use a 4×4 transfer matrix to study the optical properties of the structure. Results show that the compound structure can result in an intense Faraday rotation effect and gain transmission mode, and form multiple laser outputs with elliptical or circular polarizations in a certain range of structural parameters. In addition, for some specific structural parameters and wavelengths, the structure can produce an ultra-intense laser with circular polarization.
