Abstract

Topological insulators (TIs) are newly discovered state of quantum matter, which is characterized by ordinary insulating bulk states and gapless metallic surface states. Among them three TIs have been used as a saturable absorber (SA) in mode-locked fiber lasers: bismuth telluride (Bi₂Te₃), bismuth selenide (Bi₂Se₃) and antimony telluride (Sb₂Te₃). Soliton [1] and stretched-pulse mode-locking regimes [2] have already been presented with the use of a TI, but there were no reports on the generation of dissipative solitons at 1.5 μm.
