    • An optical apparatus and methods for operating on a polarization state of a light beam using a compound tri-state non-reciprocal rotator having two Faraday rotators. A first Faraday rotator rotates the polarization state into one of two partially rotated states at angles +α, −α, where α=22.5°, and the second Faraday rotates the polarization state from one of the partially rotated states into one of three fully rotated states at angles +2α, 0, −2α. A polarization selection mechanism guides light in the three fully rotated states differently to enable various devices and different modes of operation. For example, the polarization selection mechanism can generate a tri-state output in the form of two distinct output beams corresponding to two of the three fully rotated states, and an overlapping pair of output beams obtained when the compound tri-state non-reciprocal rotator produces the third of the three fully rotated states. The various methods permitted by the invention permit simple and cost-effective multicasting switches and methods.
    • 一种使用具有两个法拉第旋转器的复合三态不可逆旋转器来操作光束的偏振状态的光学装置和方法。 第一个法拉第旋转器将偏振状态转换成角度为αα,αα,其中α= 22.5°的两个部分旋转状态中的一个,并且第二法拉第将偏振状态从部分旋转状态中的一个旋转到三个完全旋转 状态为角度+ 2alpha,0,-2alpha。 偏振选择机构以三个完全旋转的状态引导光,以使各种装置和不同的操作模式不同。 例如,偏振选择机构可以产生三个完全旋转状态中的两个的两个不同的输出光束形式的三态输出,以及当复合三态不可逆旋转器 产生三个完全旋转状态中的三分之一。 本发明允许的各种方法允许简单且具有成本效益的多播交换机和方法。
