Driven by new two-dimensional materials, great changes and progress have taken place in the field of ultrafast photonics in recent years. Among them, the emerging single element two-dimensional materials (Xenes) have also received much attention due to their special physical and photoelectric properties including tunable broadband nonlinear saturable absorption, ultrafast carrier recovery rate, and ultrashort recovery time. In this review, the preparation methods of Xenes and various integration strategies are detailedly introduced at first. Then, we summarize the outcomes achieved by Xenes-based (beyond graphene) fiber lasers and make classifications based on the characteristics of output pulses according to the materials characterization and nonlinear optical absorption properties. Finally, an outlook of the future opportunities and challenges of ultrafast photonics devices based on Xenes and other 2D materials are highlighted, and we hope this review will promote their extensive applications in ultrafast photonics technology.
近年来，在新型二维材料的推动下，超快光子学领域发生了巨大的变化和进步。其中，新兴的单元素二维材料（Xenes）因其特殊的物理和光电特性，包括可调谐宽带非线性饱和吸收、超快载流子恢复率和超短恢复时间，也受到了广泛关注。在这篇综述中，首先详细介绍了Xenes的制备方法和各种集成策略。然后，我们总结了基于Xenes（超越石墨烯）的光纤激光器所取得的成果，并根据材料表征和非线性光学吸收特性，按照输出脉冲的特点进行了分类。最后，重点展望了基于Xenes和其他二维材料的超快光子学器件未来的机遇和挑战，我们希望这篇综述将推动它们在超快光子学技术中的广泛应用。
