Model for estimating the properties of mechanically induced long-period fiber grating based on polarization and applied pressure

Abstract

This study proposes a model for estimating the properties of mechanically induced long-period fiber gratings (MLPFGs) based on polarization and applied pressure. The model arises from the linear relation between the applied pressure and coupling coefficients of MLPFGs through utilization of Jones matrix analysis. The transmission property of a fabricated MLPFG can be easily estimated using the relation between the applied pressure and coupling coefficients obtained from the measured spectra of MLPFGs. The estimated spectra around the resonance wavelengths based on our proposed model show good agreement with the measured ones.
