Two‐dimensional Ag₂S – with its large absorption coefficient, broadband optical response, extraordinary metal‐like ductility, high plastic deformation strain, unique layered structure, and very low solubility – offers a platform for achieving tremendous success in various fields of photonics. In article number 1901762, Xiaohui Li and co‐workers experimentally realize ultrashort soliton operation based on a 2D Ag₂S saturable absorber integrated into a fiber laser. The 229th harmonic soliton molecule achieves a repetition rate of 1.1 GHz in the telecommunication band.
