This project aims to develop compact cold atom sensors—such as atomic clocks, accelerometers, and gyroscopes—using photonic integrated circuits (PICs). Traditional cold atom systems are bulky, occupying large optical benches or the size of multiple washing machines. The goal is to significantly reduce their size, weight, power consumption, and cost to enable real-world deployment.
The work will leverage the silicon-nitride photonic platform at the University of Glasgow’s James Watt Nanofabrication Centre (JWNC), which includes advanced components like low-loss waveguides, microring resonators, polarisation optics, narrow linewidth lasers, and MEMS vapour cells. The project will use red and blue detuned light to trap and guide cold atoms via the evanescent field of waveguides.
Students will receive training in industry-standard design tools (Lumerical, Synopsys), cleanroom fabrication, and advanced photonics measurement. The project is aligned with the UK Quantum Hub for Position, Navigation and Timing, offering access to scientific, social, and professional development events, including skills training and international conference participation.
