摘　　要：针对传统互耦半导体激光器接入天基网络的次序容易出现混乱、颠倒等问题,提出结合改进遗传算法的互耦半导体激光器接入天基网络次序的优化。采用基于激光位移传感器,阶段选择局部状态,将求解接入天基网络次序优化方案的问题变换成小规模问题,选择天基网络激光器接入点,给出互耦半导体激光器的非线性动力学方程,实现互耦半导体激光器接入天基网络次序的优化,仿真实验结果分析说明,所提激光器接入天基网络次序优化方法的复杂度低,性能优。Aiming at the disorder and reversal of the order of traditional mutual coupled semiconductor laser accessing to space-based networks,the optimization of the order of mutual coupled semiconductor lasers accessing to the space-based network is proposed. Using a laser displacement sensor based on phase selection of local state will transform the problem of accessing order optimization scheme of space-based network into small scale problems. Choosing the access point of space-based network laser,giving out nonlinear dynamic equations of mutually coupled semiconductor lasers to realize the optimization of mutually coupled semiconductor lasers with space-based network accessing order. The simulation results show that the proposed method has low complexity and high performance.
