基于数字化偏振态发生器和米勒矩阵法的高速偏振模色散测量

Abstract

A polarization-mode dispersion (PMD) measurement system using a pair of polarization-state generators (PSGs) is demonstrated. Based on the saturation characteristics of magneto-optic rotators, the PSG can be digitally controlled, ensuring high-speed and highly repeatable generation of five distinct polarization states. Thus, the PSG can make full use of the advantage of the Mueller matrix method of PMD measurement. The experimental result shows that the system has good measurement repeatability and potential for field testing.
