Abstract

Simulation results of few-mode signal propagation over silica graded multimode optical fibers with periodical slowly varying core diameter, excited by laser source, are represented. Weakly-guiding irregular multimode fibers with axialsymmetric graded index profile under central defect, local fluctuations and single outer cladding are considered. It is supposed, the core diameter varies slowly along fiber length according to sine function. The period of sine function is more then 10⁶ times greater then fiber core diameter. Solution is based on proposed time domain model of piece-wise regular multimode fiber link under few-mode signal propagation under laser source exciting. Model takes into account differential mode delay, higher-order mode chromatic dispersion, mode mixing and power diffusion. Some results of pulse dynamics calculation during propagation over described fiber with periodical slowly varying core diameter are represented.
