Bandwidth-Tunable Mode-Locked Fiber Laser Enabled by Hetero-Core Offset-Spliced GIMF Saturable Absorber

We demonstrate a passively mode-locked erbium-doped fiber laser utilizing a hetero-core offset-spliced gradient-index multimode fiber (GIMF) structure. The all-fiber saturable absorber is fabricated by offset-splicing two GIMF segments with mismatched core diameters of 62.5 μm and 50 μ...
