| 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。

| Abstract: | 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. |
