Abstract

We present a model with which to calculate the index increase induced in standard single-mode fiber by hydrogen loading. Also, we propose that the dominant products of reaction in UV-written hydrogenated standard communication fibers are GeE′ and Si-OH. Based on the above models, we calculate the Bragg wavelength shifts that are due to hydrogen diffusion out of the fiber gratings. The relative effective index change that is due to hydrogen dissolved in fiber can be as much as 6 × 10-4 if standard telecom fiber is hydrogen loaded with a concentration of ∼1.44 mol.%. Theoretical results agree with experimental results.
