grating

powerful platform for simulating FBG behavior, enabling detailed analysis, optimization, and innovative development. This article aims to provide a comprehensive overview of fiber Bragg grating simulation in MATLAB, exploring the core principles, modeling techniques, pra

ce, gratings can be apodized or chirped: Apodization: gradually varying the index modulation to reduce sidelobes. Chirping: varying the period along the length to broaden or shift the reflection band. In MATLAB, the
