This PhD project at the University of Southampton, within the EPSRC Centre for Doctoral Training in Quantum Technology Engineering, focuses on the manufacture of photonic and quantum technologies using ultra-precision diamond machining. The research aims to develop core components for superconducting, photonic, and atom/ion trap quantum systems, which are essential for quantum sensing and quantum computing. The project involves designing, fabricating, and testing atom and ion trap systems, working closely with experimentalists to demonstrate quantum sensing and computing capabilities. Key areas include the development of miniature vacuum cells from silicon, silica, and sapphire, featuring optical windows, integrated mirrors, and electrical/vacuum feedthroughs; fabrication of integrated optical waveguides and large area tilted Bragg gratings to couple light out of waveguides for micro-atom traps; and the creation of freeform micro-optics such as lenses, mirrors, and resonators to enable more compact and efficient quantum photonic systems. Students will benefit from substantial training in scientific, technical, and commercial skills, and will collaborate with leading experts in academia and industry, including partner groups within the UK National Quantum Technology Programme. The Southampton group offers a highly supportive research environment and world-leading expertise in quantum technologies, photonics, and micro-fabrication. Funding is available on a competitive basis, with UK students eligible for a 4-year UKRI TechExpert tax-free stipend of approximately £31,000 per year, and studentships at the UKRI base rate for EU, Horizon Europe, and international students. Overseas students with external funding are also encouraged to apply. Entry requirements include an undergraduate degree with at least a UK 2:1 honours or international equivalent. Applications should be submitted via the University of Southampton online portal, including a CV, two academic references, degree transcripts/certificates, and English language qualification if applicable. The university is committed to equality, diversity, and inclusivity, and supports applicants seeking part-time study. The closing date for applications is 31 July 2026, with an earlier deadline of 31 March 2026 for international applicants.
