Дослідження залежності оптико-геометричних характеристик мікроструктурованого оптичного волокна від механічних впливів

Abstract

This work investigates the influence of mechanical deformation on the optical and geometrical characteristics of microstructured optical fibers. A model of the fiber cross-section with air holes in the cladding was considered, and the effect of bending and structural distortion on effective refractive index, chromatic dispersion and bending loss was analyzed. The dependence of the effective refractive index difference on the ratio of air-hole diameter to pitch was evaluated. The obtained results confirm high sensitivity of microstructured fibers to external mechanical influence and demonstrate the necessity of optimizing their geometrical parameters
