我们提出并讨论了一个中红外（中红外）透明的柔性束的基础上1200光纤的核心组成的Ge30As13Se32Te25硫系玻璃和氟化乙烯丙烯（FEP）的包层的制造和表征。中红外光纤束是使用堆叠和拉伸方法制造的。玻璃和包层之间的高折射率对比度允许在中红外透明的硫族化物玻璃芯内的良好导模的强场限制。由于聚合物包层提供的高衰减，可能易于串扰的高阶模遭受高损耗。此外，FEP包层赋予束机械柔性。定性热成像评估后，我们还提出并讨论了光纤束的实验损耗测量，并将其与通过建模获得的值进行比较，以得出制造束的潜在前景及其可能的改进的结论。
We present and discuss the fabrication and characterization of a Mid-Infrared (Mid-IR) transparent flexible bundle based on 1200 fibers whose cores consist of a Ge30As13Se32Te25 chalcogenide glass and the cladding of a Fluorinated Ethylene Propylene (FEP). The Mid-IR fiber bundle was manufactured using the stack and draw method. The high index contrast between the glass and the cladding allows for strong field confinement of the well guided modes within the chalcogenide glass core transparent across the Mid-IR. Higher order modes, which could be prone to cross talk, suffered high losses thanks to the high attenuation offered by the polymer cladding. Additionally, the FEP cladding confers the bundle mechanical flexibility. Following a qualitative thermal imaging assessment, we also present and discuss the experimental loss measurements of the fiber bundle and we compare them to values obtained through modelling to conclude on the potential prospect of the manufactured bundle and its possible improvements.
