在这里，它证明了堆叠和拉伸的方法可以扩展到不寻常的材料关联和轮廓几何，以产生具有前所未有的功能的纤维组件。这种方法依赖于将平板氧化物玻璃幻灯片堆叠成预制件，然后将预制件热拉长成数十米长的带状纤维，并保持横截面率。介绍了其制作方法。为了说明该方法的通用性，展示了一组具有不同几何形状和功能的光纤，包括用于化学传感的纯玻璃裸芯光纤，以及插入金属电极后的H形多腔结构和紧凑的玻璃-金属光纤光学探测器，用于通过光纤尖端等离子体光谱进行气体分析。人们相信，这种新方法将为设计具有增强功能的创新、复杂的多材料纤维平台提供一种有吸引力的、直接的解决方案。
Here, it is demonstrated that the stack-and-draw approach can be expanded to unusual materials association and profile geometries to generate fiber assemblies with unprecedented functionalities. This approach relies on the stacking of flat oxide glass slides into a preform, which is then thermally elongated into tens-of-meters-long ribbon fibers with preserved cross-section ratio. Fabrication methodology is introduced. In order to illustrate the versatility of the method, a panel of fibers with diverse geometries and functions is exposed, including glass-only exposed-core fibers for chemical sensing and, upon the insertion of metal electrodes, H-shaped multi-cavity structures and compact, glass-metal fiber optical detectors applied to a gas analysis by means of fiber-tip plasma spectroscopy. It is believed this new approach will offer an attractive, straightforward solution for designing innovative, complex multimaterial fiber platforms with enhanced functionalities.
