作者描述了一种在光波通信波段工作的快速光谱偏振计，能够在几毫秒内并行测量数百（最多数千）个光谱成分的偏振状态和偏振度。在本文中，该设计采用了快速开关铁电液晶，用于100 μ s尺度的极化元件选择。色散元件和阵列探测器用于波长平行传感。覆盖带宽可以从单个波分复用信道扩展到100 nm以上，并在1 ms内验证了256个光谱偏振测量。最后，采用标定算法使测量误差最小化。该仪器为高速光波通信中与极化相关的损伤的监测和补偿提供了前所未有的传感能力
The authors describe a fast spectral polarimeter operating in the lightwave communications band capable of measuring both state-of-polarization and degree-of-polarization of hundreds (up to thousands) of spectral components in parallel within milliseconds. In this paper, the design incorporates fast switching ferroelectric liquid crystals for polarization component selection on the 100-mus scale. Dispersion elements and an arrayed detector are used for wavelength-parallel sensing. Bandwidth of coverage can be scaled from a single wavelength-division multiplexed channel to more than 100 nm, and 256 spectral polarization measurements in under 1 ms are verified. Finally, a calibration algorithm is used to minimize measurement error. This instrument offers unprecedented sensing capability relevant to the monitoring and compensation of polarization-related impairments in high-speed lightwave communications
