使用具有非线性、不可逆传输函数的电光系统产生高复杂度光信号

Highly-complex optical signal generation using electro-optical systems with non-linear, non-invertible transmission functions

José J. Suárez-Vargas, Bicky A. Márquez, Jorge A. González

摘要:

我们提出了一个方案,其中一个静态的非线性,不可逆的传输函数进行的电光马赫-曾德尔调制器产生高度复杂的光学混沌。该方案允许低维带限混沌信号的确定性变换到更高维的宽带谱结构,而不使用任何延迟元件或反馈。标准的基准测试表明,所有考虑的复杂性指数大大增加,由于这种转换在一个控制的方式。这种机制允许设计具有极其复杂的混沌输出的简单光电延迟振荡器。

英文摘要:

We present a scheme whereby a static non-linear, non-invertible transmission function performed by the electro-optic Mach-Zehnder modulator produces highly complex optical chaos. The scheme allows the deterministic transformation of low-dimensional band-limited chaotic signals into much higher-dimensional structures with broadband spectra and without using any delay elements or feedback. Standard benchmark tests show that all the considered complexity indices are highly increased due to this transformation in a controlled fashion. This mechanism allows the design of simple optoelectronic delayed oscillators with extremely complex chaotic output.
