Abstract :
The Verdet constant in annealed optical fiber current sensors has been measured at wavelengths from 636 to 1320 nm. The measurements are fitted to two models, one classical and the other an expansion of the classical model that includes a nonlinear term. These measurements and models are compared to previous measurements made in optical fiber and bulk SiO2. Our measurements have an average accuracy of ±0.6% and an average measurement uncertainty of ±0.5% over the 636 to 1320 nm range
