A four-hole tellurite microstructured optical fiber (MOF) was designed and fabricated based on TeO2–Bi2O3–ZnO–Na2O (TBZN), and the fiber loss was 0.1 dB/m@1550 nm. Based on a 3 m tellurite MOF, dispersive wave (DW) generation and evolution was experimentally investigated at the pump wavelengths of 1778 nm, 1812 nm, and 1878 nm. With the increase of the average pump power, DWs trapped by optical solitons were observed at the blue edge wavelength, but their formation became more and more difficult with the pump wavelength shifting far away from the zero-dispersion wavelength. The variation pattern of center wavelengths and peak powers of the fundamental optical solitons and DWs were investigated: the center wavelength distribution satisfied the group velocity matching; the peak power of the fundamental DW gradually exceeded that of the fundamental optical soliton with the increase of the average pump power. Furthermore, using the generalized nonlinear Schrodinger equation, simulation on the generation of DWs and optical solitons was carried out at 1778 nm, 40 mW, the result of which agreed well with the experimental observation. This investigation is instructive for DW applications in tunable laser sources, wavelength conversion, and time frequency metrology.

亚碲酸盐微结构光纤中色散波产生和演化的实验研究

基于TeO2–Bi2O3–ZnO–Na2O（TBZN）设计并制造了一种四孔碲酸盐微结构光纤（MOF），光纤损耗为0.1 dB/m@1550 nm。基于 3 m 碲酸盐 MOF，在 1778 nm、1812 nm 和 1878 nm 的泵浦波长下实验研究了色散波 (DW) 的产生和演化。随着平均泵浦功率的增加，在蓝边波长处观察到被光孤子捕获的DW，但随着泵浦波长远离零色散波长，它们的形成变得越来越困难。研究了基本光孤子和DW的中心波长和峰值功率的变化规律：中心波长分布满足群速度匹配；随着平均泵浦功率的增加，基波DW的峰值功率逐渐超过基波光孤子的峰值功率。此外，利用广义非线性薛定谔方程，在1778 nm、40 mW处对DWs和光孤子的产生进行了模拟，结果与实验观察结果吻合较好。这项研究对于可调谐激光源、波长转换和时频计量中的 DW 应用具有指导意义。
