摘要：
In this study, we analyzed the loss formation in bent single-mode optical fibers using a semi-analytical method, which is a combination of conformal mapping and coupled-mode theory based on the two-layer step-index optical fiber model. The pure bend loss results were compared to those reported in the existing literature. The advantage of using this method is that it provides insight into the mode held behavior and loss formation in bent fibers and accurately presents the power distribution in the cross section of the fibers.
