Abstract
The investigations in this paper apply the Nelder-Mead simplex optimization algorithm, using MATLAB’s fminsearch function, to improve the design of Raman amplifiers achieving a flat on-off gain profile and anti-resonant hollow-core fibers minimizing their confinement- and scattering loss values. Specialized solvers were developed for each application and integrated with the optimization algorithm. Results demonstrate that this approach effectively identifies optimal design parameters, leading to significant improvements in gain flatness for Raman amplifiers and substantial reductions in confinement- and scattering losses for hollow-core fibers. This study highlights the effectiveness of the Nelder-Mead method for optimizing complex optical device designs through simulation.
