About the project

We are looking for a PhD student to join our interdisciplinary team of students, postdocs, and senior researchers developing systems for quantum technologies.

Nonlinear parametric photonics is used to control quantum systems and as sources for photonic qubits. Researchers at the University of Southampton have led the development of quasi-phase-matched non-linear systems. This project will combine novel fabrication approaches with well-developed commercial materials to expand the operation range into the blue and ultra-violet wavelength regions for atom and ion trap quantum systems.

In this project, you will design, fabricate and test parametric devices. You will also work with other experimentalists to apply these devices to quantum systems. If you are interested in a PhD and are looking to do computer modelling and have the required skills, the project can also be adjusted for this. Potential areas of research include:

  • The development of blue and UV-generating parametric waveguides for the control of atom and ion trap systems. These will generate blue and UV light from infrared light sources. 
  • Investigating type II non-linear waveguides for single photon generation. Including the use of coupled cavities to enhance the efficiency. You will then use these findings to develop prototype systems that can be used in photonic quantum computing.

Both these areas will involve the fabrication of devices with the Southampton team, optical testing and metrology and working with our partners to apply the devices to quantum systems.    

If you are interested in quantum technologies, photonics and micro-fabrication, you would be highly suitable for this project. You will benefit from our world-leading expertise in these fields and enjoy working in a highly supportive environment in our Southampton group and collaborating with partner groups around the country within the UK National Quantum Technology Programme.
