Gas-induced differential refractive index guidance in hollow core fibres

本项目重点研究充气空心芯纤维（HCFs）的特性和应用。具体来说，你将研究我们最近发现的一种新效应，即通过在光纤的芯区和包层区之间施加不同的气体压力，可以显著地改变HCF的光学特性。您将探索在各种应用中利用这种效应的潜力，该项目将涉及纤维设计元素以及基于实验室的实验工作。在这个研究领域有很大的创新空间，这项工作适合有创造力和自我激励的候选人。将有机会与内部和外部合作伙伴合作，并在国际会议和主要期刊上发表成果。

This project is focussed on characterisation and applications of gas-filled hollow core fibres (HCFs). Specifically, you will investigate a novel effect which we have very recently discovered, whereby the optical properties of a HCF can be dramatically modified by applying differential gas pressure between the core and cladding regions of the fibre. You will explore the potential to exploit this effect in various applications, and the project will involve elements of fibre design as well as lab-based experimental work. There is substantial scope within this research area for innovation and this work will suit a creative and self-motivated candidate. There will be opportunities to collaborate with internal and external partners and to publish results at international conferences and in leading journals.
