Detailed Documentation
By implementing the Runge-Kutta method to solve long-period fiber gratings, we can accurately determine their transmission characteristics, which provides critical insights into the grating's performance parameters and practical applications. The numerical approach involves solving coupled-mode differential equations through fourth-order Runge-Kutta integration, where key functions handle refractive index modulation and phase-matching conditions. This analysis facilitates the design and optimization of fiber grating sensors for diverse applications including environmental monitoring, medical diagnostics, and structural health monitoring. Therefore, in-depth investigation of long-period fiber grating transmission properties carries significant theoretical importance and practical value for advanced photonic device development.
