Paper Abstract

A new way leading to estimate Fiber Bragg Gratings (FBG) parameters is presented. We describe calculating influence of accuracy of FBG execution on their basic characteristics. In this paper we report and present an FBG element as an optical fiber sensor. An FBG quality characterize two mainly essential parameters. There are Full Width at Half Maximum to stand for FWHM (also presented as Δλ) and reflection index to stand for R. We examine influence of accuracy of FBG with reference to following quantity: modulation of the refraction index Δn and the grating period Λ. On the basis of well known analytical relationship which describe FWHM and R we have estimated influence of FBG construction on above parameters. After obtain final analytical dependences we make suitable graphs to depict all calculations.
