Recent development of soliton technology, “solitonics” is described. New soliton families are introduced, as the coupled soliton, the supersoliton, etc. Novel systems of soliton transmission, such as the coupled transmission, the paired transmission, the phase conjugated transmission, etc. are proposed. These multiplex transmission system are effective to reduce the transmission jitters and to enhance the channel capacity. Switching and logic devices are proposed by using asymmetrical nonlinear coupler. The logic element has a property of AND-OR gates but it cannnot be realized to be small size. The WDM soliton transmission is now very promising for ultra-high capacity communication. The nonlinear coupling between the solitons with different wavelengths are analyzed and a “kidnapping” effect, in which one soliton carries off a part of another soliton.
