Revolutionary ultrathin optical devices for imaging

Flat optics have revolutionized design concepts in photonics, providing a compact platform to develop unusual ultrathin optical devices with multiple functionalities. This project will focus on the application of these devices in imaging, including polarimetric imaging and edge imaging.

The candidate will work in the Experimental Nanophotonics group led Dr Xianzhong Chen at Heriot-Watt University. This group is dedicated to the fundamental physics of optical metasurfaces and ultrathin optical devices for imaging, defence, display and information processing. Current research interests include metalenses, holograms, structured light beams, 3D polarization manipulation, polarimetric imaging and edge imaging. Our research has enabled the discovery of new phenomena and the development of new prototype devices, which are essential for future technologies. We have built connections with local industry, including STMicroelectronics, Renishaw and Ceres Holographics.

Applicants must have or expect to have a first-class degree or equivalent in physics or engineering course and be strongly motivated with the drive required to pursue 3.5 years of intensive theoretical and practical work. The ideal candidate has a good knowledge of optics and photonics and experience in a laboratory environment is expected.

Heriot‑Watt’s Institute of Photonics and Quantum Sciences (IPaQS) is a thriving environment for PhD research, having a total of 160 academics, postdocs, PhD and EngD students working full‑time in the general photonics field. Heriot‑Watt is based in a modern environment on the outskirts of Edinburgh (Scotland, UK), with excellent transport links to the centre of one of Europe’s most exciting cities. Heriot‑Watt was recently awarded a UK Engineering and Physical Sciences Research Council (EPSRC) Centre for Doctoral Training in Applied Photonics, cementing Heriot‑Watt’s reputation as a centre of excellence in photonics, and providing PhD students with an even more attractive environment for study, as well as enhanced training opportunities.
