摘要
从非线性薛定谔方程出发,推导了光纤非线性系数和光纤非线性相移之间的关系,提出了一种基于QPSK光传输系统的非线性系数测量方法,并进行了仿真实验。仿真结果表明,该方法能准确地计算出非线性系数,对寻找更精确更快速的非线性系数测量方法有一定的参考意义。
From the nonlinear Schrodinger equation,the relationship between fiber nonlinear coefficient and phase shift is derived. A nonlinear coefficient measurement method based on QPSK system is proposed. Simulation result shows that this method enables more simple and efficient nonlinear coefficient calculation, it has a certain reference value for finding more accurate and rapid measurement of the nonlinear coefficient.
