This PhD project, based at the University of Southampton within the EPSRC Centre for Doctoral Training in Quantum Technology Engineering, focuses on nonlinear photonics for quantum technologies. The research aims to create advanced parametric photonic devices that interface light with atoms, ions, and detectors in quantum systems. By combining innovative fabrication techniques for nonlinear waveguides with commercial materials, the project seeks to extend device operation into the ultraviolet and mid-infrared regions, enabling practical applications in quantum systems. Key research areas include developing blue/UV-generating parametric waveguides for atom and ion trap control, investigating nonlinear waveguides for single and paired photon generation (with coupled cavities to enhance efficiency), and creating up-conversion devices for single photon imaging in the mid-infrared, relevant to environmental monitoring and life-science imaging. The project involves design, fabrication, metrology, and optical testing, with opportunities to collaborate with an interdisciplinary team of students, postdocs, senior researchers, and industrial partners. The research aligns with the EPSRC Quantum Technology Hub for Sensing, Imaging and Timing (QuSIT) and the UK National Quantum Technology Programme. Students will receive substantial training in scientific, technical, and commercial skills, and benefit from world-leading facilities and expertise. Funding is competitive: UK students receive a 4-year UKRI TechExpert tax-free stipend of around £31k per year, while EU, Horizon Europe, and international students may receive studentships at the UKRI base rate or apply with external funding. Applicants must hold at least a UK 2:1 honours degree or international equivalent. The university supports equality, diversity, and inclusivity, considers personal circumstances, and offers part-time study options. The application deadline is 31 July 2026 (31 March 2026 for international applicants).

This PhD project, based at the University of Southampton within the EPSRC Centre for Doctoral Training in Quantum Technology Engineering, focuses on developing ultra-low-loss photonic components for quantum networks. The research aims to create advanced quantum memories, switchable delay lines, and large entangled quantum states, which are essential for interfacing quantum computers and networks. Unlike traditional optical telecoms, quantum technologies cannot rely on amplifiers to compensate for losses, making every photon critical. The project will explore technical approaches such as all-optical fibre-based systems and integrated atomic vapour devices, offering opportunities to design, fabricate, and test these systems. Students will work in a collaborative environment alongside other PhD students, postdocs, and senior researchers, benefiting from Southampton's world-class fabrication facilities and expertise. The project is suitable for candidates interested in quantum technologies, photonics, nonlinear optics, micro-fabrication, or computer modelling. Substantial training in scientific, technical, and commercial skills is provided, along with opportunities to collaborate with industrial partners and academic researchers across the UK National Quantum Technology Programme. UK students receive a competitive UKRI TechExpert stipend of approximately £31k per year for four years, with studentships at the UKRI base rate available for EU, Horizon Europe, and international students. Overseas students with or seeking external funding are encouraged to apply. Applicants must hold at least a UK 2:1 honours degree or international equivalent and submit a CV, two academic references, degree transcripts/certificates, and proof of English language proficiency if required. The University of Southampton is committed to equality, diversity, and inclusivity, and supports applicants seeking part-time study. The application deadline for UK students is 31 July 2026, while international applicants must apply by 31 March 2026.
