Theory
The nonlinear schrödinger equation (NLSE) is widely used to describe the nonlinear propagation of pulses in a single mode optical fibre. Thousands of papers have been written about the applications of this equation, but the vast majority of them are concerned with numerical methods of solution as only a few analytical solutions are known. We have recently (in association with Vladimir Kruglov) discovered a whole new class of self similar solutions to this equation with many potential applications in how power fibre amplifiers. Another area of investigation concerns the development of the theory behind the phenomenon of optical parametric amplification in single mode fibres. This work is of particular application to photonic crystal fibres (PCFs).


Experiments
Experimental work currently being pursued includes the study of parametric optical amplification in PCFs, supercontinuum generation in PCFs, use of the FROG technique for optical pulse characterisation in the communications bands, soliton pulse generation, the construction of self similar amplifiers and compressors, and the construction of new devices for high speed optical communications systems.
