Anomaly of mode field in multistep index profile multimode fiber.
A remarkable anomaly of a mode field in multistep-index multimode fibers was observed. It is demonstrated by a finite-element modal analysis that the highest field peak locations of guided modes with the anomaly shift toward the core-cladding boundary drastically.
