Bend insensitivity of large-mode-area CLING fibers (Conference Presentation)
Author(s): Krysta A. Boccuzzi; John R. Marciante

Paper Abstract

Cladded linear index graded (CLING) fibers are designed to reduce the spatial overlap between the fundamental mode and higher-order modes in order to mitigate thermal mode instability. Numerical simulations were used to study the effects of bending on loss and mode deformation in CLING fibers. It was found that CLING fibers experience mode deformation at a >10x tighter bend radius than conventional large-mode-area (LMA) fiber. The CLING fiber therefore retains all the advantages of an LMA fiber but at small bend radii, enabling much larger mode areas than allowable in conventional LMA fibers (currently 25-µm core).
