Electrically Tunable Metasurface Members of the CPDS group have recently co-authored a paper on a liquid crystal based dynamically tunable metasurface for amplitude modulation. The metasurface consists of coupled subwavelength grating fingers, which provide alignment for the liquid crystal without the need for an...

CPDS group are recruiting a Research Assistant/Associate in Optical Engineering to conduct research and development on novel high- precision optical measurements in photonic devices, in particular, spatial light modulators with subpixel-accuracy hologram setting for precise beam steering, system design and implementation...

Non-Convex Optimization for Inverse Problem Solving in Computer-Generated Holography Computer-generated holography is a promising technique that modulates user-defined wavefronts with digital holograms. Computing appropriate holograms with faithful reconstructions is not only a problem closely related to the fundamental...

Revolutionising Dynamic Optical Control In the rapidly evolving field of optical engineering, the integration of metasurfaces with dynamic control elements remains a pivotal challenge. Wenhan Zhang, a researcher from the CPDS group, has fabricated a liquid-crystal Huygens metasurface, leading to an unprecedented level of...
