Abstract

We present a simple and compact saturable absorber (SA) fabricated by filling a hollow-core anti-resonant fiber (HC-ARF) with MXene Ti₃C₂T_x. The proposed SA exhibits exceptional nonlinear saturable absorption property with a modulation depth of 30% at 2 μm and a remarkably low insertion loss of 3.5 dB, which is realized by manipulating the MXene Ti₃C₂T_x thickness coated to the outer tubes of the HC-ARF. Conventional soliton mode locking can be achieved by incorporating the SA into a thulium-doped fiber laser. The pulse width is 1.72 ps and the pulse signal to noise ratio is larger than 70 dB. To the best of our knowledge, it is confirmed for the first time that the filling HC-ARF with MXene Ti₃C₂T_x as SA can achieve mode-locking ultrashort pulses operating in the 2 μm band. We believe this work can open a new avenue for exploring the integration of HC-ARF filled with various two-dimensional materials as SA devices.

利用Mxene Ti3c2Tx填充空心抗谐振光纤作为可饱和吸收体的掺铥锁模光纤激光器

采用MXene Ti3C2Tx填充空心抗谐振光纤（HC-ARF）制备了一种简单紧凑的饱和吸收材料（SA）。通过在HC-ARF的外管上涂覆MXene Ti3C2Tx厚度，该结构具有优异的非线性饱和吸收性能，在2 μm处的调制深度为30%，插入损耗为3.5 dB。传统的孤子模式锁定可以通过将SA加入到掺铥光纤激光器中来实现。脉冲宽度为1.72 ps，脉冲信噪比大于70 dB。据我们所知，首次证实以MXene Ti3C2Tx作为SA填充HC-ARF可以实现工作在2 μm波段的锁模超短脉冲。我们相信这项工作可以为探索HC-ARF填充各种二维材料作为SA器件的集成开辟新的途径。

期刊介绍： The Journal of Lightwave Technology is comprised of original contributions, both regular papers and letters, covering work in all aspects of optical guided-wave science, technology, and engineering. Manuscripts are solicited which report original theoretical and/or experimental results which advance the technological base of guided-wave technology. Tutorial and review papers are by invitation only. Topics of interest include the following: fiber and cable technologies, active and passive guided-wave componentry (light sources, detectors, repeaters, switches, fiber sensors, etc.); integrated optics and optoelectronics; and systems, subsystems, new applications and unique field trials. System oriented manuscripts should be concerned with systems which perform a function not previously available, out-perform previously established systems, or represent enhancements in the state of the art in general.
