Abstract:
A novel fiber design of large mode area (LMA) all-glass leakage channel fibers (LCF) with triangular core is proposed. The effective single mode behavior and bend characteristics of the fiber are numerically investigated. The designed LCFs can achieve LMA larger than 1400 μm2, effective single mode operation and low bend loss by carefully choosing the diameters of the fluorine-doped silica rods.
