Paper Abstract

This work presents some results of earlier on performed optimization of refractive index profile for 42 μm core 16-LPmode optical fiber for next-generation optical networks. Here special profile form provides total differential mode delay (DMD) reducing over all the mode staff under desired enhanced mode effective area. We propose method for simulation of "real manufactured" few-mode optical fiber (FMF) core geometry, differing from desired optimized structure by core asymmetrical ellipticity and refractive index profile deviation, including local fluctuations. Some results of following analysis of considered optimized FMF with inserted geometry distortions, performed by earlier on developed modification of rigorous mixed finite-element method showed strong DMD degradation that requires additional higher-order mode management. Therefore this work also presents results of design of mode division multiplexer channel precision spatial positioning scheme at FMF core end that provides one of the potentiality solution of described DMD degradation problem concerned with "distorted" core geometry due to features of optical fiber manufacturing techniques.
