Semiconductor photonic integration in
UV/Blue
wavelength band
Supervisor: Professor Frederic Gardes
Co-Supervisor: Dr Yaonan Hou

Photonic integration is becoming a key solution for next-generation information technologies. Compared with the existing technologies in the near-infrared wavelength band, UV/blue light integration is emerging as an attractive subdivision in integrated photonics. With the advantages of a smaller footprint and a larger bandwidth, UV/blue integrated systems hold the promise in the vast applications including, but not limit to, visible light communications, augmented reality (AR)/virtual reality (VR) systems, inter-satellite communications, light detection and ranging (Lidar), high-density data storage, quantum photonic chips, chemical/biological photonic chips, and non-Von Neumann photonics.  

The objective of this innovative research project is to realize a hybrid system comprising UV/blue light sources fabricated from the third-generation wide band gap semiconductors (group III-nitride materials) and the photonic components based on rapidly developing Si photonics (e.g., waveguides, optical couplers, modulators, detectors).   

The successful candidate will join a cutting-edge research group (https://gp-iv-photonics.org/) in the Optoelectronics Research Centre (ORC) at the University of Southampton. Within this interdisciplinary project, you will develop a solid knowledge and practical skills in semiconductors and photonics. All the work will be carried out at the ORC, home to a number of modern cleanrooms and advanced testing labs.  The work is mainly composed of the following parts, 1) design and fabrication of III-nitride laser diodes; 2) optimization and fabrication of waveguides, photonic couplers and photodetectors; 3) characterization of the electrical and optical properties of both the individual devices and the integrated systems.

If you wish to discuss any details of the project informally, please contact Dr Yaonan Hou (yaonan.hou@soton.ac.uk), or Prof. Frederic Gardes (fg5v@ecs.soton.ac.uk).

Entry Requirements:  A very good undergraduate degree (at least a UK 2:1 honours degree, or its international equivalent) in physics, electronic engineering, materials science, or a related discipline.  

Funding:  A fully-funded PhD place on this project is available for eligible UK applicants. For EU  and international applicants, please see the details from the following link, https://www.southampton.ac.uk/courses/funding/international.page. Overseas students who have secured external funding are also welcome to apply.
