摘要：The spectral response of the uniform FBG with different grating parameters such as grating length andindex change are provided and discussed. The coupled mode theory is a suitable tool for analysis and obtainingquantitative information about the spectrum of a fiber Bragg grating. The coupled mode equations can be obtained andsimplified by using the weak waveguide approximation. The spectrum characteristics can be obtained by solving thesecoupled mode equations. In this paper simulation of FBG has been carried out to analyze the spectral characteristics ofthe FBG. An optical FBG is being simulated with the help of advanced software module such as the R soft and themodeled sensor is evaluated for the grating and different efficiency of various grating shape parameters, modulationdepth,etc. The relationship between the maximum reflectance, 3dB bandwidth and centre wavelength with gratingparameters are also given and discussed. Optimization and improvement of the system can be realized by using thesimulation results. Since the present work not only deals with theoretical aspects of FBGs but also leads to thedevelopment of simulation tools which can be used in the area of communications and sensors.
