We present a novel device, an arrayed waveguide Sagnac interferometer, that combines the flexibility of arrayed waveguides and the wide application range of fiber or integrated optics Sagnac loops. We form the device by closing an array of wavelength-selective light paths provided by two arrayed waveguides with a single 2 x 2 coupler in a Sagnac configuration. The equations that describe the device's operation in general conditions are derived. A preliminary experimental demonstration is provided of a fiber prototype in passive operation that shows good agreement with the expected theoretical performance. Potential applications of the device in nonlinear operation are outlined and discussed.
我们展示了一种新型器件——阵列波导萨格纳克干涉仪，它结合了阵列波导的灵活性以及光纤或集成光学萨格纳克环的广泛应用范围。我们通过在萨格纳克配置中用一个单2×2耦合器封闭由两个阵列波导提供的波长选择光路阵列来构成该器件。推导了描述该器件在一般条件下运行的方程。给出了一个处于无源运行状态的光纤原型的初步实验演示，其结果与预期的理论性能吻合良好。概述并讨论了该器件在非线性运行方面的潜在应用。
