摘　　要：运用有限差分法数值模拟了布拉格孤子在光纤光栅中的传输,计算和分析了光栅色散与光栅损耗对布拉格孤子传输的影响。结果表明,光栅色散渐减使脉冲的峰值增大,光栅损耗使脉冲展宽,两者对布拉格孤子在光纤光栅中的传输具有互补性,即两者对布拉格孤子的传输作用相反。在一定的情况下,两者使布拉格孤子在光纤光栅中稳定地传输。Transmission of the Bragg solitons are simulated with the finite-difference scheme in fiber Bragg gratings. Effects of dispersion decreasing and loss on Transmission of Bragg solitons in fiber Bragg gratings is analyzed by simulating numerically the transform of Bragg solitons. According to the numerical results, dispersion decreasing makes peak power of pulse heighten, fiber Bragg Grating loss makes width of pulse extend, and we have found that dispersion decreasing and fiber Bragg Grating loss took contrary action on the transmission of Bragg solitons in fiber Bragg gratings, they make Bragg solitons transmitting stably in fiber Bragg Gratings.
