液体光子晶体光纤正常色散区高相干超连续谱的产生
Highly coherent supercontinuum generation in the normal dispersion liquid-core photonic crystal fiber
在这篇文章中，我们设计了一种纤芯为二硫化碳的液芯光子晶体光纤，该光纤具有极高的非线性系数，并且在1200 nm到2500 nm 波段具有全正色散。通过求解广义非线性薛定谔方程，我们数值仿真了该光纤中产生的超连续谱，并对超连续谱的产生机制进行了深入研究。此外，我们还研究了不同泵浦参数对产生的超连续谱的谱宽及其相干性的影响，这对于超连续谱研究中参数的选择和质量优化具有极其重要的意义。总之，我们的提供了一种新的高相干超连续谱的产生方法，这些成果必将在光相干断层扫描、频率梳和超短脉冲产生等应用研究中发挥重要作用。
In this paper, a liquid-core photonic crystal fiber (LCPCF) with small hollow-core filled by chalcogenide material CS2 is designed. The supercontinuum (SC) generation in such a LCPCF with nonlinear coefficient of 3327 W-1okm-1 at 1550 nm and wide normal dispersion regime spanning from 1200 to 2500 nm is numerically studied by solving the generalized nonlinear Schr?dinger equation. The influences of the pump pulse parameters on the SC spectral width and coherence are demonstrated, and the optimum pump condition for the SC generation is determined. Our study work can provide an alternative way for obtaining highly coherent SC, which is important for the applications in optical coherence tomography, frequency combs, and ultrashort pulse generation.
