摘　　要：利用有限差分法对在均匀光纤光栅中布拉格孤子的形成和相互作用进行了数值模拟,研究了在一定输入峰值功率下形成的布拉格孤子,以及二个布拉格孤子、三个布拉格孤子之间的相互作用和能量交换。结果表明,布拉格孤子间隔很小时(Ts=1.0T0)会相互吸引与相互排斥,随着间隔增大,布拉格孤子间发生明显的能量转移,形成一定规律的布拉格孤子演化过程。Formation and interaction of Bragg solitons are simulated with the finite-difference scheme in a uniform fiber Bragg Grating. We have investigated Bragg soliton formed on a certain peak power, and we have also investigated interaction and energy exchange between Bragg solitons. According to the numerical results, the interaction of Bragg soiltons for small interval （Ts = 1.0T0 ） is repulsive and attractive. As the interval increases ,obvious energy exchange of Bragg solitons takes place, and evolvement of Bragg solitons is formed regularly.
