摘　　要：任何含有有源器件的微波放大电路在一定情况下都会表现出非线性特性。针对光反馈半导体激光器收发系统微分方程组的特点,根据龙格-库塔算法的思想和模型中的特点,提出了对当前迭代式中所需要的之前斜率值的估计算法,并对发射与接收信号进行了仿真,结果表明该算法可以使得接收端与发射端快速收敛一致,并能有效对该类系统进行仿真分析。Microwave amplifying circuits composed of active devices have nonlinear characteristics in certain conditions. According to Runge-Kutta algorithm and the features of differential equations for semiconductor laser transimitting and receiving system, an approach for computing gradients in iterative formula is presented, and the transmitting and receiving signals are simulated. The simulation results show that the quick convergence uniformity at both input and output terminals can be acquired by this algorithm. And this algorithm can also be used to simulate all this kind of systems effectively.
