A novel configuration for measuring femtosecond polarization mode dispersion (PMD) with a pi-shifted Sagnac interferometer is studied. The advantages of this configuration include a response that is independent of the orientation of the device under test. This independence allows characterization of the first-and second-order PMD by measurement of the wavelength dependence of the differential group delay and of the orientation of the device's principal states of polarization. The method provides an extension of the dynamic range of the Sagnac interferometer technique to few-femtosecond PMD measurement.
研究了一种利用π相移萨格纳克干涉仪测量飞秒偏振模色散（PMD）的新型配置。这种配置的优点包括响应与被测设备的取向无关。这种独立性使得通过测量差分群延迟的波长依赖性和设备主偏振态的取向来表征一阶和二阶PMD成为可能。该方法将萨格纳克干涉仪技术的动态范围扩展到了飞秒级的PMD测量。
