In this work a photonic crystal fiber made of a heavy metal oxide glass with optimized dispersion profile is proposed for supercontinuum generation in a broad range of wavelengths in the near-infrared, when pumped by a mode-locked fiber-based laser. The fiber is modelled and optimal geometrical parameters are selected to achieve flat and low dispersion in the anomalous regime. Supercontinuum generation in the range of 0.76⁻2.40 µm, within the dynamics of 30 dB, when pumped at 1.56 µm with 400 fs⁻long pulses and an average power 660 mW is possible. The applicability of such fibers is also discussed.
在这项工作中，提出了一种由重金属氧化物玻璃制成的光子晶体光纤，具有优化的色散分布，可在近红外波长范围内通过基于锁模光纤的激光进行超连续谱产生。对光纤进行建模，并选择最佳的几何参数，以在反常区域实现平坦和低色散。在 1.56 µm 处用 400 fs 长的脉冲和平均功率 660 mW 泵浦时，在 0.76⁻2.40 µm 的范围内可以实现 30 dB 动态范围内的超连续谱产生。还讨论了这种光纤的适用性。
