About the project
Nonlinear parametric photonics is used to control quantum systems and as a source for photonic qubits. We have led the development of quasi-phase-matched non-linear systems. This project combines novel fabrication approaches with established commercial materials to expand the operation range into the ultra-violet and mid-infrared wavelength regions for quantum photonics.
In this project, you will design, fabricate and test parametric devices for quantum technologies, working with our interdisciplinary team of students, postdocs, and senior researchers to apply these devices to quantum systems. If you are looking to do computer modelling and have the required skills, the project can also be adjusted for this.
Areas of research include:
- development of blue/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. Applying this to develop prototype systems that can be used in photonic quantum computing
- developing up-conversation devices (combining two low-energy photons) for single photon imaging in the mid-infrared for environmental monitoring and life-science imaging
These areas involve fabrication of devices, optical testing and metrology, and working with our partners to apply the devices to quantum systems. This project will closely work with the UK Quantum Technology Hub in Sensing, Imaging and Timing (QuSIT) and will have opportunities to engage with the other partners on the project.
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 the Optical Engineering and Quantum Photonics Group, while collaborating with partner groups around the country within the UK National Quantum Technology Programme.
