Paper Abstract
Large flattened mode optical fiber with raised index ring around the outer edge of the fiber core has been fabricated
through modified chemical vapour deposition process to raise the threshold for non-linear interaction in high power laser
fiber. The conversion of the fundamental mode shape from a Bessel function to a top hat function, enhances the effective
area of the core intersected by the mode without increasing the physical size of the core. The shape of the fundamental
mode is observed to be strongly dependent on the width of the raised index ring from the modal analysis. Suitable fiber
parameters have also been estimated through the modal field analysis. Fabrication process steps have been optimized to
achieve the desired fiber parameters. Modal field distribution, transmission properties and bending loss of the fabricated
fibers have been characterized.
