Solitons are a fascinating topic for study and a major source of
interest for potential application in optical communication.
Possibly the first observation of a soliton occurred in 1838 and
was made by a clerical gentleman riding a horse along a canal
towpath. When a barge under tow came to a stop alongside him the
bow wave did not stop, but continued to travel on its own for
several miles with no change in shape. At the time this unusual
phenomenon was not understood and remained unexplained. Interest
was revived with the development of optical fibres and the
realisation that at the high intensities possible in their very
small cores the onset of non-linear effects could modify the
propagation characteristics in a significant way. In a seminal
paper in 1973 Hasegawa and Tappert solved a non-linear Schrodinger
equation for fibre propagation and found solutions for solitary
waves, i.e. solitons. Since then advances have been very rapid
resulting in a much better understanding of a wide variety of
soliton effects, and, crucially, the realisation that soliton
propagation can be used to potentially great advantage in practical
long-distance systems. There is, as a result, a wealth of
theoretical and experimental research in progress all over the
world. At NTT (Japan) a pule-code-modulated soliton train has been
transmitted at 10Gbit/s over one million kilometres with zero
error! Perhaps all long-distance, large bandwidth communication
problems have been solved for ever. This book gives a clear account
of the theory and mathematics of solitons travelling in optical
fibres. It is written by the authority on the subject.
