Breathing solitons in optical fiber links
Gabitov I., Turitsyn S.K.
We introduce the concept of "breathing" solitons to describe optical-pulse dynamics in transmission lines with passive compensation of fiber chromatic dispersion. The "breathing" pulse can be used as the information carrier. The presented theory is complementary to the concept of the guiding-center soliton. It is shown that an average bright soliton can propagate in the system with large variations of dispersion, including segments with high normal dispersion.
