We investigate the electronic structure, as well as gain and loss mechanisms in these and related material systems. We also investigate how the photon mode structure can be engineered through a variety of different approaches.
The research is theory-driven but with significant experimental component. It spans basic science through to investigations of fundamental processes limiting present day devices, and includes design and modelling of new and optimised devices.
