Selective Excitation of Circular Helical Modes in Graded Index Fibers

Authors: S. Al-Sowayan


The impact of selective excitation of circular helical modes of graded-index fibers on its capacity is analyzed using a model for propagation delay variation with launch offset and angle that resulted from misalignment of source and fiber axis. Results show promising technique to improve graded-index fiber capacities.
