    • Improved optical devices, systems, and methods for selectively directing optical signals generally based on a Mach-Zehnder interferometer. Through accurate control of the phase relationship, the Mach-Zehnder interferometer allows optical signals to either be cumulatively combined so as to enhance the transmitted signal strength, or destructively combined so as to effectively prevent transmission from an optical signal port. This phase relationship can be controlled using a nonreciprocal device having a pair of retarder plates disposed along one of the two legs of the Mach-Zehnder interferometer so as to provide an optical isolator or circulator.
    • 改进的光学装置,系统和方法,用于通常基于马赫 - 曾德干涉仪来选择性地引导光信号。 通过对相位关系的精确控制,马赫 - 策德尔干涉仪允许光信号被累积地组合,以增强发射信号强度,或者破坏性地组合,以便有效地防止从光信号端口的传输。 该相位关系可以使用具有沿Mach-Zehnder干涉仪的两条腿之一布置的一对延迟板的不可逆装置来控制,以便提供光隔离器或循环器。
