项目摘要

Functional glass fiber has been the key component in a broad variety of optical devices, ranging from passive waveguiding in, e.g., telecommunication and data transfer, to active functionality in fiber light sources, optical amplifiers, sensors, filters and switches. However, for decades, the technological platform has been limited to a relatively small number of principal fiber architectures and, in particular, chemical compositions, where silica and silica-based glasses are still the most prominent fiber material. This has largely been due to fabrication limits and limits of material compatibility, which prevented exploitation of exotic glass properties such as, e.g., the extreme optical nonlinearity of chalcogenides or metal-doped glasses, with the processing stability and optical performance of silica. These so-called hybrid glass fibers today represent one of the major challenges for materials development and processing, as they enable pushing the limits of physical property engineering to beyond what is presently known. For example, they would enable extreme values of numerical aperture or, subject of the present proposal, extreme combinations of functional and passive material architectures for tailored profiles of physical properties. Filling glass-forming liquids (assisted through pressure or surface tension) into the micro- or nanobores of silica-based photonic crystal fiber or capillary devices has recently been introduced as a highly promising platform for fabricating the next generation of hybrid glass fiber devices. A standing issue in this emerging approach to dedicated optical glass fiber processing is, however, the tailoring of local materials properties. Such in line structuring, for example, the generation of dielectric gradients, optical gratings, grids or specific plasmonic activity, on the other side, is the prerequisite for the next step towards solving future device needs. Here, the present key is to obtain a dedicated understanding of such in line processing, its underlying thermokinetic and photochemical principles, and its physical limits. The present proposal therefore targets a fundamental understanding of the local precipitation of metallic nanostructures in hybrid optical fibers through external fields. We intend to explore the basic materials aspects which control particle precipitation inside an optical fiber device, providing mechanistic information on limits of reaction kinetics, lateral resolution, photostability and, most importantly, optical activity of such glass fiber. This shall need to a new generation of active fiber devices which combine the optical properties of silica with the plasmonic activity of photosensitive, metal-doped low-melting glasses.

功能玻璃纤维一直是各种光学设备的关键部件，从电信和数据传输中的无源波导到光纤光源、光放大、传感器、滤光器和开关中的有源功能。然而，几十年来，技术平台一直局限于相对较少的主要纤维体系结构，特别是化学成分，其中二氧化硅和硅基玻璃仍然是最突出的纤维材料。这在很大程度上是由于制造限制和材料兼容性的限制，这阻碍了对奇异玻璃特性的开发，例如硫化物或金属掺杂玻璃的极端光学非线性，以及二氧化硅的加工稳定性和光学性能。这些所谓的混杂玻璃纤维今天是材料开发和加工的主要挑战之一，因为它们能够将物理特性工程的极限推向超越目前已知的极限。例如，它们将实现数值孔径的极值，或者，本提案的主题，功能和被动材料建筑的极端组合，以实现物理特性的定制轮廓。将玻璃形成液(通过压力或表面张力辅助)填充到二氧化硅基光子晶体光纤或毛细管器件的微孔或纳米孔中，最近被引入为制造下一代混合玻璃光纤器件的一个非常有前途的平台。然而，在这种新出现的专用玻璃纤维加工方法中，一个长期存在的问题是当地材料性能的剪裁。另一方面，这种线内结构，例如产生介电梯度、光学栅格、栅格或特定的等离子体活动，是解决未来器件需求的下一步的先决条件。在这里，目前的关键是对这种在线加工、其潜在的热动力学和光化学原理以及其物理极限有一个专门的了解。因此，本提案旨在从根本上理解混合光纤中通过外场的金属纳米结构的局部析出。我们打算探索控制光纤器件中粒子沉淀的基本材料方面，提供关于反应动力学、横向分辨率、光稳定性以及最重要的光学活性的机理信息。这将需要新一代的有源光纤器件，它将二氧化硅的光学特性与光敏、金属掺杂的低熔点玻璃的等离子体活性结合起来。
