Fast Computational Algorithm for the Weakly Coupled FMF Model

The transmission of optical waves within Few-Mode Fiber (FMF) is challenged by the influences of dispersion, attenuation, various nonlinear effects, and inter-modal crosstalk arising from suboptimal transmission conditions. Therefore, this paper introduces a fast computation algorithm for the weakly...

Shrnutí:The transmission of optical waves within Few-Mode Fiber (FMF) is challenged by the influences of dispersion, attenuation, various nonlinear effects, and inter-modal crosstalk arising from suboptimal transmission conditions. Therefore, this paper introduces a fast computation algorithm for the weakly coupled FMF model. Building upon the split-step Fourier algorithm, this method subdivides the computation step size into smaller intervals, each computed independently using parallel algorithms. Additionally, the inter-modal crosstalk terms are represented as matrix-vector multiplications and accelerated using matrix libraries. Experimental verification demonstrates a 37% efficiency improvement compared to the split-step Fourier algorithm.
