Bi<sub>2</sub>Te<sub>3</sub> Topological Insulator for Domain-Wall Dark Pulse Generation from Thulium-Doped Fiber Laser
We have experimentally demonstrated domain-wall (DW) dark pulses from a thulium-doped fiber laser incorporating a topological insulator saturable absorber (SA). The bulk-structured Bi<sub>2</sub>Te<sub>3</sub> was used as the SA, which was constructed on a fiber ferrule platf...
