In the paper, a spirally filled solid core chalcogenide-based photonic crystal fibre is proposed, which is engineered to obtain a flattened broad anomalous dispersion profile. The spectrum spanning in the wavelength region from 1.5 to 3.6 μm was achieved by pumping hyperbolic secant pulses with a peak power of 350 W and 85 fs pulse duration, at a wavelength of 2.5 μm, in the optimized design of the fibre. This chalcogenide-based photonic crystal fibre of length 100 mm can be used for wavelength converter between light and microwave. It can find its application as up–down link applications between light and microwave, the light-microwave transducer in LiFi, and WiFi links.

As2S3-硼硅酸盐硫属化物玻璃基色散工程光子晶体光纤在中红外区域产生宽带超连续谱的研究

在该论文中，提出了一种螺旋填充的实芯硫属化物基光子晶体光纤，该光纤经过设计以获得平坦的宽异常色散分布。在光纤的优化设计中，通过泵浦峰值功率为 350 W、脉冲持续时间为 85 fs、波长为 2.5 μm 的双曲线正割脉冲，可以实现跨越 1.5 到 3.6 μm 波长区域的光谱。这种长度为 100 mm 的硫族化物基光子晶体光纤可用于光与微波之间的波长转换器。它可以作为光和微波之间的上下行链路应用、LiFi 中的光-微波换能器和 WiFi 链路找到其应用。
