Prof Keith Blow

I studied at Cambridge University where I was awarded a BA in Physics and Theoretical Physics in 1978. I then joined the Theory of Condensed Matter Group of the Cavendish Laboratory and received a Ph.D. for studies on Deep Impurities in Semiconductors in 1981.

I joined the optics division of BT Labs in 1981 and worked on the theory of non-linear optical propagation effects in fibres, principally solitons. This work developed into optical switching and the first demonstration of soliton switching in non-linear optical loop mirrors. In 1990 I set up a group working on quantum optical properties and non-linear spatial optics as well as continuing work on all-optical processing which is currently concerned with ways of using and manipulating the information that can be sent over the enormous bandwidth of optical fibres. In 1999 I moved here to the Photonics Research Group at Aston to continue working on optical networks and optical computation.  In 2003 I formed the Adaptive Networks Communications Research Group to study ad-hoc sensor networks, applications of dynamic hardware and mobile systems.
