Graphical User Interface Calculator for FBGS Performance Optimization Based on New Window Formulas

Abstract

In this research paper, we develop on one hand a novel theoretical approach to optimize the performance of Fiber Bragg Grating Sensor (FBGS) based on an automated MATLAB-based program, and on the other hand, we propose a new graphical user interface including all design parameters of the FBGS to optimize automatically its window profile based on the sensing system requirement. The main objective of this approach is to obtain the higher reflected power from the FBGS as long as side lobes are kept below the required level. All formulas of the proposed method of optimization are programmed using the Coupled Matrix Theory (CMT) and the Transfer Matrix Method (TMM), which describe the light behavior within the FBGS. The proposed easy-to-use graphical interface allows also researchers to determine easily all parameters required for high FBGS performance providing a high precision and accuracy of numerical results. The proposed theoretical approach has been compared with the window profiles proposed by other authors. All results demonstrate the efficiency of the proposed method.
