High Sensitivity, Multispecies Raman Gas Sensing in Hollow Core Fibres

本项目旨在开发一种基于新型空芯光纤技术的超高灵敏度、多物种拉曼气体传感器。该传感器将适用于诸如环境感测（例如，温室气体）和高级医疗诊断（例如，用于早期和非侵入性疾病诊断的呼吸分析）的应用。空芯光纤是气光相互作用的激发平台，因为它们可以填充有目标气体样品，以在受限气体分子和引导光之间提供巨大的相互作用长度。传感器将检测来自包含在空芯光纤中的气体样品的拉曼散射光，这将提供目标气体的唯一光谱指纹。这个博士项目将涉及广泛的活动，主要是实验性的，但具有一定的灵活性，这取决于申请人的兴趣，并可能适合来自物理，工程或化学背景的申请人。成功的学生将与经验丰富的研究人员一起工作，可以使用各种设备，并与外部合作伙伴合作，以最大限度地发挥其工作的影响。该项目涉及与工业合作伙伴IS-仪器公司密切合作，该公司专门从事拉曼仪器。

This project aims to develop an ultra-high sensitivity, multispecies Raman-based gas sensor based on novel hollow core fibre technology. This sensor would be suitable for applications such as environmental sensing (e.g. of greenhouse gases) and advanced medical diagnostics (e.g. breath analysis for early and non-invasive disease diagnosis). Hollow core fibres are an exciting platform for gas-light interactions as they can be filled with the target gas sample to provide a huge interaction length between the confined gas molecules and the guided light. The sensor will detect Raman scattered light from the gas sample contained in the hollow core fibre which will provide a unique spectral fingerprint of the target gas. This PhD project will involve a wide range of activities, primarily experimental but with some flexibility, depending on the interests of the applicant, and could suit applicants from a physics, engineering or chemistry background. The successful student will work with experienced researchers, have access to a wide range of equipment and work with external partners to maximise the impact of their work. This project involves working closely with an industrial partner, IS-Instruments, who specialise in Raman instrumentation.
