Pilot Sample

This work presents results of researhes of fabricated pilot sample of chiral few-mode optical fiber (FMF) with induced twisting of 10 and 66 revolutions per meter, core diameter 11 µm (that almost corresponds to standard singlemode optical fibers), typical “telecommuniction” cladding diameter 125 µm and improved height of step refractive index profile. Proposed few-mode optical fiber supports 4 guided modes over “C”-band. We considered design and selection of desired technological parameters, based on results of computations, performed by both rigorous and approximation methods. Spectral curves of dispersion parameters are reprented as well as results of experimental measurements near-field laser beam profile and spectral and pulse responces of laser-excited optical signals.
