Abstract
(Invited) Recently, progress in optical soliton communication has been very rapid, and it shows a great potential for opening a new field in high-speed communication. The optical soliton, which was first proposed by Hasegawa and Tappert in 1973,1 propagates stably over long distances in an optical fiber without waveform distortion by balancing the group-velocity dispersion of the fiber with its nonlinearity, the so-called self-phase modulation. One of the main factors that limits communication speed is the group-velocity dispersion in the transmission fiber. However, optical solitons make it possible to construct a dispersion-free high-speed optical communication system by using the nonlinearity in the fiber.
