摘要
通过修正描述半导体激光器的动力学模型,给出了具有横向效应的半导体激光器的动力学方程,并分析了横向效应对半导体激光器输出特性的影响。在此基础上,进一步研究了具有横向效应的半导体激光器输出信号的同步传输技术。结果表明,考虑横向效应后,半导体激光器的输出呈现新的时空混沌态,且对初始值非常敏感。同时,无论是利用半导体激光器进行单通道信号的同步传输还是多通道信号的同步传输,其传输性能均十分稳定。该项同步技术十分简单,非常易于实际应用。
In this paper,a dynamic equation of a semiconductor laser with transverse effect is given by modifying the dynamic model,and the influence of the transverse effect on its output characteristics is analyzed.On this basis,the synchronization transmission technology of a semiconductor laser’s output signal with transverse effect is further studied.The results show that the output of the semiconductor laser presents a new spatiotemporal chaotic state after considering the transverse effect,and is very sensitive to the initial value.At the same time,whether the synchronization transmission of single-channel or multi-channel signals is carried out by a semiconductor laser,its transmission performance is very stable.The synchronization technology is very simple and easy to apply in practice.
