| 摘 要： | 光纤色散特性是支撑光纤孤子通信的决定性因素。比较了目前的几种色散补偿方案后,着重对相位共轭控制的色散控制方式进行了分析研究,该方式利用光纤非线性四波混频产生与输入光脉冲信号相位共轭的输出光脉冲信号,光脉冲的频谱以泵浦光频为中心进行反转,构建成相位共轭器,实现了对放大自发辐射(ASE)噪声、孤子相互作用与色散波等的控制,达到提高系统传输速率、距离和通信容量的目的。

| Abstract: | The dispersive characteristic of fiber is a key factor for the fiber soliton communication system. A compensation method of phase conjugate control for dispersion is studied after comparing several dispersive compensation methods. With nonlinear-effect of four wave mixing, output optical pulse signals whose phase conjugates with the input pulse signals can be generated. The optical pulse spectrum is reversed around the center of the pumping frequency. As a result, the phase conjugate controller can reduce Amplified Spontaneous Emission (ASE) noise, restrain interaction effect of the solitons and control dispersive wave, etc. |
