Keith J. Blow
Keith J. Blow studied at Cambridge University, where he was awarded his B.A. degree in physics and theoretical physics in 1978 and his Ph.D. degree for studies on deep impurities in semiconductors in 1981. He joined BT Labs in 1981 and worked on the theory of nonlinear optical propagation effects in fibres, principally solitons and their response to perturbations such as higher-order dispersion, polarisation, and the Raman component of the nonlinear response. This work developed into the applications of solitons to optical switching and the first experimental demonstration of soliton switching in nonlinear optical loop mirrors. In 1990, he set up a group working on quantum optical properties and nonlinear spatial optics. Since 1996, he has been working on the application of bit serial processing techniques to all-optical networks and optical computing. In 1999, he was appointed Professor of photonic networks at Aston University, UK. He is currently working on nonlinear all-optical signal processing and the application of advanced coding techniques in nonlinear transmission systems.
