摘要

我们报告了用于中红外超连续发生的镓-锑-镓玻璃基光子晶体光纤（PCF）结构的设计和理论研究。通过调整包层区域的气孔直径和间距，我们可以控制光纤的色散特性。优化的结构设计提供了 5.2 μm 的零色散波长。对于长度为 8 毫米、泵浦波长为 5 μm 的光纤，当使用峰值功率为 4.9 kW 的 50 fs 正割双曲脉冲进行泵浦时，拟议的结构设计可产生跨度为 1.5-14 μm 的超宽带超连续谱。拟议的 PCF 设计应有助于生物医学成像、超连续光源、生物扫描和光学相干断层扫描。

Supercontinuum generation in Ga-Sb-S chalcogenide-based PCF using optofluidic approach

We report the design and theoretical study of a Ga-Sb-S chalcogenide glass-based photonic crystal fiber (PCF) structure for mid-infrared supercontinuum generation. The proposed design is engineered by adjusting the diameter of air holes in the cladding region and pitch, giving us control over the dispersion characteristics of the fiber. The optimized structure design offers the Zero Dispersion Wavelength of 5.2 μm. When pumped with 50 fs secant hyperbolic pulses of peak power 4.9 kW, for a fiber of length 8 mm at pump wavelength of 5 μm, the proposed structure design produces an ultra-broadband supercontinuum spectrum spanning 1.5–14 μm. Proposed PCF design should be helpful in, biomedical imaging, supercontinuum sources, biosesning, and optical coherence tomography.
