Raman spectroscopy provides unique molecular 'fingerprints' for chemical and biological sensing, but its inherently weak signal limits sensitivity for trace gases and dilute samples. This EngD project aims to overcome these challenges by integrating quantum photonic technologies with advanced Raman instrumentation to create quantum-enhanced Raman spectrometers.

Through this integration, the project seeks to significantly enhance sensitivity and enable new modes of operation beyond the reach of conventional Raman systems. During the project student will explore single-photon, time-correlated Raman technology, where the time of arrival of each Raman photon is measured with respect to the emission light. Such technology allows for measurement of the exact location of Raman scatterer and extremely efficient suppression of fluorescence and other backgrounds. The proposed work will push the boundaries of optical sensing, with applications in gas detection, energy systems, environmental protection, and transport safety.

The student will gain hands-on experience developing and testing new optical systems — from laboratory design to real-world validation.

The student will have access to state-of-the-art Fraunhofer CAP facilities in Glasgow’s Technology and Innovation Centre and work collaboratively across academia and industry. The programme offers extensive professional development through technical, commercial, and leadership training, along with opportunities to publish research outcomes, present at conferences, and travel internationally.

The student will be based at, and work within Fraunhofer Centre for Applied Photonics's molecular sensing team, collaborating closely with and jointly supervised by:

• Dr David Stothard and Dr Roman Spesyvtsev (Fraunhofer Centre for Applied Photonics)
• Dr David Li (Department of Biomedical Engineering, University of Strathclyde)
• Dr Ralf Bauer (Department of Electronic & Electrical Engineering, University of Strathclyde)

Students with physics, engineering, or photonics backgrounds are welcome to apply for this opportunity.

About Fraunhofer Centre for Applied Photonics

Fraunhofer CAP is a not-for-profit Research and Technology Organisation (RTO) and is the UK’s first Fraunhofer Research Centre — part of Europe’s leading applied research organisation. Based within the University of Strathclyde’s Technology and Innovation Centre in the heart of Glasgow, we collaborate with industry and academia to transform research into solutions that benefit society.

Our work spans renewable energy, quantum technologies, space, health, security, and beyond — helping companies bring ideas from the lab to the real world.

We are an inclusive, supportive, and dynamic team that values curiosity, integrity, and collaboration. We welcome applicants from all backgrounds who share our passion for scientific discovery and innovation.

While working at Fraunhofer CAP, the student will be fully supported by Dr Li’s and Dr Bauer’s research teams.

Each studentship combines advanced academic research with practical, applied projects. You’ll gain hands-on experience in cutting-edge photonic technologies and work alongside leading scientists, engineers, and industry partners. Our projects are designed to challenge you, stretch your abilities, and prepare you for a meaningful research or innovation career.

Fraunhofer CAP is a friendly and encouraging ”Great Place To Work” accredited workplace with high rankings for ‘Development’ and ‘Women’. Find out more about diversity management at Fraunhofer.
