Free Space Optical Communications ('Optical Wireless') has the potential to provide THz of unlicensed bandwidth for in-building communications. Research in the group concerns the characteristics of the optical wireless channel, and the devices and systems required to use it.

The research in Ultrafast electronics is based on exploiting the properties of novel materials to develop new high speed devices for both analog and digital applications. Current research in the group centres on development of anlysis tools based on ultrafast optical systems with which to test digital and analogue ultrafast circuits. Recent developments in superconducting devices which exploit both the fluxionic and the josephson effect at frequencies >100GHz have motivated much of this work.

Radio communications offers high availability communications links. The explosive growth interest and usage over recent years has increased demands for wireless broadband access across a wide range of applications from simple voice, through video and high speed data communications. Wireless technology offers roaming and mobility in addition to flexible deployment strategies. The last mile of the communication for fixed networks has long been a cost sensitive area and technologies which enable ease of deployment and high performance are extremely attractive. The work in the radio domain seeks to establish new radio techniques and technologies which provide the ability to understand and characterize shorter range radio communications, particularly in urban and cluttered multipath environments. To this end the main thrust of the work is aimed at a full understanding of the complex propagation conditions and using this to develop novel network and terminal architectures and transceivers to deliver reliable high capacity flexible short range links for both fixed and mobile networks.
