Characteristics of directional couplers with lapped multimode fibers
Abstract:
Measurements of characteristics and a theoretical ray-optics analysis were made on directional couplers prepared by connecting a pair of lapped multimode fibers. Various measured characteristics such as branching ratio, excess insertion loss, and mode conversion agreed fairly well with calculated values. From these results a way was found to lessen the excess insertion loss and the branching ratio.
