A major activity of the Photonics Group since joining the Advanced Technology Institute has been the use of ultrashort pulses for the study of dynamics of electrons and light waves on a femtosecond time-scale. This time scale is one that covers the time it takes for electons and photons to interact; for electrons and phonon (quantum packets of sound or heat) to interact; and for chemical reactions to occur and so on.

Our primary interests include:; small energy electronic transitions in semiconductors (e.g. intersubband transitions, narrow band gaps etc) studied with a Free Electron Laser (Prof Ben Murdin); dynamics of spins in semiconductors using circularly polarised pulses (Prof Ben Murdin and Dr Steven Clowes); development of semiconductor spintronic devices (Dr Steven Clowes); single atom spintronic devices for quantum information (Prof Ben Murdin); femtoscecond dynamics of interacting electrons and photons in semiconduictor laser diodes (Prof Jeremy Allam); 1D diffusion of excitons along carbon nanotubes (Prof Jeremy Allam).
