【摘要】 利用对称分步傅里叶方法(SSFM)求解非线性薛定谔方程(NLS),分析了非线性双芯光纤耦合器中不同芯层内孤子脉冲的相位对能量交换特性的影响,只要初始注入孤子信号的相位差选择恰当,可以通过一个芯层的弱孤子脉冲来控制另一芯层内强孤子脉冲的传输行为,得到不同的开关特性。更多还原

【Abstract】 By using symmetried split-step Fourier method(SSFM) for solving the nonlinear Schrdinger equation(NLS),the characteristics of phase-sensitive soliton switching in optical fiber couplers have been studied.Transmission behaviors of the main pulse will be dramatically controlled by the initial phase of a relative weak soliton in another fiber core.Different switching properties will be obtained,provided the initial solitons phases into two fiber cores are selected appropriately.更多还原
