Limitation on effective area of large-mode-area leakage channel fibers under bent condition
The bending characteristics of two-ring leakage-channel-fibers are investigated to achieve large-mode-area and effectively single-mode operation with a practically allowable bending radius for Yb-doped fiber applications, enhancing differential bending loss >; 10-dB/m between the fundamental and higher-order modes.
