It is an exciting time to be working in optics. Previous generations of researchers have been largely limited to the use of naturally-occurring materials such as glass, etc. Recent advances in fabrication made by the integrated circuit industry have dramatically improved our ability to produce nanostructured materials. Recent years have also seen an explosion in computing power. These two developments have made it possible to design and fabricate nanostructured materials ("metamaterials") that have optical properties not present in natural materials. These have been used in the demonstration of several, previously unimaginable, phenomena, e.g. materials with negative refractive indices and "invisibility cloaks". We previously demonstrated a very thin metamaterial, termed a "metasurface", consisting of silicon nanostructures on a glass substrate (Nature Communications vol 5 5386 (2014)) . This had the unusual property of deflecting infrared light into different directions, depending on its polarization. We have recently demonstrated a metasurface that functions as both a colour printed image as well as a hologram (Advanced Functional Materials 1906415(2020)). PhD projects are available on developing advanced dielectric metasurfaces and integrating them lasers. Projects will be primarily experimental, but also with theory/simulation components.
