| 摘 要： | 本文在耦合模理论的基础上，运用有限差分法数值模拟了布拉格亮孤子在抛物线平方变迹光纤光栅中的传输特性．结果表明，输入功率和初始脉宽等初始条件的不同将导致孤子峰值强度的周期变化；合适选择输入功率和初始脉宽，可使光孤子在变迹光纤光栅中稳定传输．孤子在传输过程中始终受到抛物线平方变迹布拉格光栅的制约．

| Abstract: | On the basis of the coupled mode theory,the finite-difference method is used to simulate the transmission of Bragg bright solitons in parabolic squared-apodization fiber gratings. According to the numerical results ,it is found that some initial conditions of input power and initial pulse width may cause Bragg soliton＇s peak power to vary periodically. Transmission of Bragg solitons in parabolic squared-apod selected. The all along the ization gratings can be stable only when suitable input power and initial pulse width are transmission of solitons is resticted by parabolic squared-apodization fiber Bragg gratings process. |
