Multi-wavelength fiber lasers have the advantages of low cost, easy integration with fiber systems, and wide tunable range, which is the key component of dense wavelength division multiplexing (DWDM). 2D MoTe2 micro-sheets have drawn lots of researchers’ attention due to their anisotropic layered structure and high optical adsorption. Evanescent-field (EF) devices have many applications in multi-wavelength and high-power fiber lasers. The integration of MoTe2 micro-sheets and an EF device is able to combine their advantages. Here, we report on the experimental observation of multi-wavelength solitons based on EF interaction with polarization-sensitive MoTe2 micro-sheet. Dual-wavelength conventional solitons (CSs) and switchable dual-wavelength dissipative solitons (DSs) are emitted by the proposed fiber laser. Different solitons can be effectively tuned by optimizing pump power and the state of the polarization controller. The proposed EF device and fiber laser are convenient and attractive in the fields of fiber-based sensing, frequency comb spectroscopy, and DWDM.

基于偏振敏感 MoTe2 微片的渐逝场器件提供的多波长孤子

多波长光纤激光器具有成本低、易于与光纤系统集成、可调范围宽等优点,是密集波分复用(DWDM)的关键组成部分。2D MoTe 2微片由于其各向异性的层状结构和高光吸收而引起了很多研究人员的关注。渐逝场 (EF) 器件在多波长和高功率光纤激光器中具有许多应用。MoTe 2微片和 EF 器件的集成能够结合它们的优点。在这里,我们报告了基于 EF 与偏振敏感 MoTe 2相互作用的多波长孤子的实验观察微单。所提出的光纤激光器发射双波长常规孤子(CS)和可切换双波长耗散孤子(DS)。通过优化泵浦功率和偏振控制器的状态,可以有效地调整不同的孤子。所提出的 EF 器件和光纤激光器在基于光纤的传感、频率梳光谱和 DWDM 领域具有方便和吸引力。
