NIR and visible structured beam generation with a dual-force mechanical long-period fiber grating
Wen-Hsuan Kuan, Xin-Yu Hou, Kuei-Huei Lin +1
This work presents tunable generation of vortex, vector, and flat-top 1060-nm NIR beams in a few-mode fiber with a dual-force mechanical long-period fiber grating. By varying the a…

Optical bistability of continuous-wave and multi-pulse phase transition within EDFL via low threshold saturable absorber
Hsuan-Sen Wang, Wen-Hsuan Kuan, Ahmed F. M. El-Mahdy +4
We demonstrate optical bistability in an erbium-doped fiber laser (EDFL) using a low saturation intensity covalent organic framework (COF) saturable absorber (SA). The COF-SA satis…
