Analyzing spectral properties of loss waves in Long-Period Fiber Gratings (LPG) through simulation approaches with code implementation insights

Detailed Documentation

This study focuses on simulating the spectral characteristics of loss waves in Long-Period Fiber Gratings (LPG). The research involves analyzing various LPG types and their loss wave properties, including interference patterns, resonance behaviors, and transmission losses. Key implementation approaches may involve coupled-mode theory calculations using MATLAB or Python, where algorithms model phase-matching conditions and grating period variations. Additionally, we investigate LPG-based fiber sensor technologies and their applications in temperature, pressure, and strain monitoring. Through numerical simulations employing transfer matrix methods or finite-difference techniques, we can better understand optical fiber sensors and their practical significance. The implementation typically involves parameter optimization loops and spectral response visualization to validate theoretical models against experimental data.
