Study On The Propagating Properties Of Soliton And The Theory Of Interaction Between Solitons

The purpose of this thesis is to study the propagation characteristics of a single picosecond optical soliton and the interaction between two optical solitons which can be used in the quantum-nondemolition measurements and optical switchs. The causing of optical soliton is discussed. The nonlinear Schrodinger equation which is use to describe the characteristics of solition is solved by the inverse scattering method and the propagating beam method. Following the interaction between two optical solitons is also discussed. The exchanges of informations with collisions of two optical solitons can be used to achieve in the quantum-nondemolition measurements both in the resonant materials and in the non-resonant materials, which is being compared the next. In the finally, a basic principle configuration of the picosecond optical soliton switch is designed, which take advantage of non-linear phase shift of the interaction primary effected by the cross-phase modulation.
