摘要利用Mach-Zehnder干涉仪实验验证了热极化光纤器件中冻结场的存在。该技术可用于测量冻结场的大小和方向。同样的技术也可用于测量非极化光纤和极化光纤的三阶非线性χ(3)。我们发现，热极化后，纤维的χ(3)增加了约2倍。
Abstract We have experimentally verified existence of the frozen-in field in thermally poled fiber devices using a Mach–Zehnder interferometer. This technique can be used to measure both the magnitude and the direction of the frozen-in field. This same technique can also be used to measure the third-order nonlinearity χ (3) of unpoled fibers and poled fibers. We find out that χ (3) of fibers has increased by a factor of ∼ 2 after thermal poling.
