  Authors : Bilkish Mondal ; Ramya M ; Chandana B; Prashant R.R.

 

Here in this paper we presented the modelling of FBG as Strain sensor for structural health monitoring application is geometrically designed in the wavelength window of 1.568- 1.580µm. Simulation has been done by using optical software RSoft (GratingMOD).

Strain

Simulation results show the design parameter at L=1500µm, reflectivity 97.26% and FWHM =1.04nm for optical sensor by using mod-grating toolbox to achieve narrow spectral response which is very much required for high sensitivity. The modelled simulated parameters implemented for Strain sensor in the range of 1-10µe for structural health monitoring.
