Plasmonics is an important emerging area of science and technology. The central idea is to use nano-structured metals to control light at the nanoscale, i.e. well below the usual diffraction limit. Many research groups around the world are now exploiting these ideas, for example in communications and solar cells. We recently showed that by placing metallic nano-objects in regular, periodic arrays, significant extra control over light can be achieved. In this project you will use state-of-the-art nano fabrication techniques to make structures that have never been created before - with the aim of uncovering a new-realm of control over light. The work will be primarily experimental in nature, but will involve some theoretical and numerical modelling work too.
