MATLAB Simulation of Fiber Bragg Grating Fabry-Perot (FBG F-P) Cavity

This package provides a MATLAB-based simulation program for Fiber Bragg Grating Fabry-Perot (FBG F-P) cavities, designed to demonstrate the matrix transfer characteristics of fiber Bragg gratings. The program implements transmission matrix methods to model light propagation through periodic grating structures, including core algorithms for calculating reflection/transmission spectra and phase responses. This simulation helps users better understand the working principles of fiber Bragg gratings and demonstrates how to leverage their unique characteristics for designing advanced sensors and optical fiber communication systems. Compared to traditional simulation approaches, MATLAB implementation offers greater convenience and speed while providing flexible parameter adjustment capabilities and comprehensive result analysis tools. The code structure includes modular functions for grating parameter definition, matrix operations, and spectral plotting, making it suitable for both educational and research applications. We hope this program proves valuable for your work and academic studies.
