Hollow core optical fibres guide light in a hollow core surrounded by a delicately engineered microstructure that can be designed to confine light into the air core and guide it therein.Hollow core fibres have many advantages over conventional optical fibres totally made of glass, such as an ultra-low latency, a much more linear behaviour, and the potential for lower loss. However, fairly little is yet known about their physical guidance mechanism and about the optimum microstructure design that can lead to ultimate performances.In this project we will study the fundamental guidance mechanisms and apply machine learning techniques combined with finite element analysis (FEA) to optimise microstructured optical fibre claddings for various applications, such as short reach data communication and power delivery. Key objectives:- Develop enhanced physical understanding of the guidance mechanism in novel hollow core fibres;- Develop a framework that incorporates both machine learning and FEA to optimise hollow core fibre cladding geometries;- Identify and incorporate fibre application specific requirements into the framework;- Generate next generation fibre designs;- In collaboration with the research group, work towards the fabrication of these designs.

空芯光纤在空芯中导光，周围环绕着精心设计的微结构，可以将光限制在空气芯中并将其引导到空气芯中。与完全由玻璃制成的传统光纤相比，空芯光纤具有许多优势，如超低延迟、更线性的行为和更低的损耗潜力。然而，人们对其物理导引机制以及可实现最终性能的最佳微结构设计知之甚少。在本项目中，我们将研究其基本导引机制，并将机器学习技术与有限元分析(FEA)相结合来优化用于各种应用的微结构光纤包层，例如短距离数据通信和电力输送。主要目标：-加强对新型中空纤维导向机构的物理理解；-开发一个结合了机器学习和有限元分析的框架，以优化中空纤维包层几何结构；-确定纤维应用的具体要求并将其纳入框架；-产生下一代纤维设计；-与研究小组合作，致力于制造这些设计。
