Optical metasurfaces for polarisation synthesis
Optical metasurfaces based plasmonic and dielectric nano-antennas provide on-demand phase control of reflected and transmitted light. This opens up unprecedented opportunities for deigning advanced optical components such as flat lenses, aberration corrected lenses, hologrammes and many others. In sensing, imaging and security, polarisation of light is of especial importance. Fast and efficient polarisation manipulation is needed in numerous applications. This PhD project will develop novel designs of optical metasurfaces for generation and active control of optical beams with complex polarisations. The project involves numerical design, nanofabrication and linear and nolinear optical characterisation of metasurfaces. We are looking for candidates with a strong background in optics and hands-on experience in optical laboratories. Knowledge of and experience in one or several of the following fields will be an advantage: optical vortex beams, ultrafast lasers, optical metasurfaces, optical forces, polarisation measurements, near-field optics, nanofabrication and numerical modelling. The successful applicant will join a vibrant, multidisciplinary group of colleagues in the Photonics & Nanotechnology Group at King’s College London working on various aspects of nanophotonics, metamaterials and nonlinear nano-optics.
