摘　　要：提出了一个复杂非线性动力学系统———交叉注入锁定半导体激光系统。针对其中最简单的两激光系统,导出了描述它的方程组,解析求解了它们具有相同自由振荡频率时的定态解。结果表明,在相同耦合条件下,锁定的频率范围比主-从方式扩大了大约一倍。从结果可以看出,即使是这种特殊系统,在锁定后频率也可能会改变。A complicated nonlinear dynamical system cross-injection locking diode lasers system is proposed. Equations are derived for the simplest system which is composed of two lasers only, and the locked steady-state analytical solutions are obtained for the simplest case in which the two lasers have the same free-running frequency without locking. The results show that with an equal coupling,locking bandwidth of cross-injection is approximately twice than that of master-slave injection and even in such special system a frequency shift may happen after the constituent lasers are locked.
