Novel Bend-Resistant Large-Mode-Area Fan-Segmented Cladding Fiber with Double Trenches
A novel double-trench-assisted fan-segmented cladding fiber (SCF) is proposed and researched. Compared with traditional fan-SCF and single-trench-assisted fan-SCF, the proposed fiber structure has a larger mode area and better high-order mode (HOM) suppression. Numerical investigations show that, when the bending radius is 20 cm, the effective mode area of the fundamental mode (FM) reaches up to 1096 μm 2 and the loss ratio between HOM and the FM is greater than 100 at a wavelength of 1.55 μm. In addition, the proposed fiber structure is insensitive to the bending orientation and its properties remain stable with a bending orientation ranging from -180° to 180°.
