NUMERICAL SIMULATIONS OF COLLISION BEHAVIORS OF OPTICAL SOLITONS IN A KERR LAW MEDIA

摘要

Optical solitons are well thought-out as natural bits for telecommunications as they have the inclination to preserve their shape over transoceanic distances In order to achieve stability, there should be a balance between the group velocity dispersion (GVD) which causes pulse broadening and the self phase modulation (SPM) which causes spectrum broadening. The time interval T_B between two adjacent bits or pulses determines the bit rate of a communication system as B =1/T_B. It is thus imperative to study how close two solitons can come without affecting each other. In this paper soliton collision in nonlinear optical fibers are investigated.
