Simulation of Fiber Bragg Grating Using Different Physical Parameters for Investigating the Effectiveness on Strain Sensor Measurements

Abstract

Abstract: This microstructure can be etched into the core of the single mode fibre by photo-inscribing it, and it has a length of a few millimetres. By illuminating the fibre with a UV laser beam and employing a phase mask to create an interference pattern in its core, this is achieved. For a variety of engineering measurements, including temperature, strain, pressure, tilt, displacement, acceleration, load, and the presence of numerous chemical and biological compounds in static and dynamic modes using Fiber Bragg Gratings (FBGs), these sensor elements are deemed outstanding. Mostly, researchers uses FBG to investigate its effectiveness in detecting physical parameters. Some people conduct research using applications and some people conduct research with simulation. For this project, the strain response of the optical FBG sensor is measured using Optiwave software with different parameters. It is shown that the various parameters represent one of the critical parameters in contributing to a high-performance fiber Bragg grating sensor. The simulated fiber gratings with different parameters were analysed and designed by calculating reflection and transmission spectra. Such simulations are based on solving coupled mode equations that describe the interaction of guided modes. It is affirmed that this model system can be used as the simulation results satisfy the previous research
