Abstract

This project presents on the analysis of strain sensing performance through software simulation and experimental setup. The bare and FBG strain sensors are tested by applying strain at the grating region of the FBG and the output of the experiment is displayed on the optical spectrum analyzer (OSA) in terms of power (dBm) and wavelength (nm). The performance of the FBGs has been evaluated by comparing the strain sensitivity and wavelength shift obtained. The FBG strain sensor has a strain sensitivity of 38.25 pm/N, which is higher than the bare FBG's strain sensitivity of 12.49 pm/N. The FBG strain sensor's experimental and simulation performance is also investigated. OptiSystem software is used to simulate the strain sensor performance. The overall results indicate the ability of FBG to be utilized as a strain sensor as the Bragg wavelength is shifted by the combination effect of effective refractive index and grating period influenced by the changes of strain
