Abstract

We have measured the Faraday effect in silica standard optical fibers in the wavelength range 458-1523 nm. An effective Verdet constant Vef that exhibits a linear dependence on the square of the optical frequency ν is defined: V(ef) = (0.142 ± 0.004) × 10(-28) ν(2) rad T(-1) m(-1). We demonstrate that the negative effects of a small linear birefringence can be minimized by adjustment of the input polarization to an optimum state.

摘要

我们已测量了波长范围在458 - 1523 nm的石英标准光纤中的法拉第效应。定义了一个有效韦尔德常数Vef，它与光频率ν的平方呈线性依赖关系：V(ef) = (0.142 ± 0.004) × 10(-28) ν(2) rad T(-1) m(-1)。我们证明，通过将输入偏振调整到最佳状态，可以将小线性双折射的负面影响降至最低。
