Abstract

In this article, a mode converter based on irregularly distributed long period fiber gratings(LPGs) is proposed. The mode conversion characteristics of LP01 mode to LP02 mode are analyzed by beam propagation method. The effects of the cross-section shape and diameter of the gratings on the mode conversion efficiency and bandwidth are analyzed. Mode conversion bandwidth between the LP01 mode and the LP02 mode is found strongly dependent on the interaction between the mode fields and the LPG section.
