论文摘要
混乱的半导体激光器已被广泛研究，用于生成真实的随机数，其优点与计算过程产生的伪数量相对于具有外部光学反馈的激光器而言。在这里，我们报告了由于几乎退化模式的相互作用，我们报告了第一个自发的混沌微型叠层。圆形六边形微叠剂的设计和演示，并以GHz为基本和一阶横向模式的GHz顺序进行调整模式间隔。四种模式在内，包括具有强大模式的退化模式将导致混乱。从激光输出功率获得5.46的激光输出功率，可获得10GB/s的真实随机数。我们的发现提供了一种新颖而简单的方法，可以为高速随机数生成创建可控制且强大的光学混乱，这也为单独的激光器中的非线性动力学铺平了道路。
Chaotic semiconductor lasers have been widely investigated for generating true random numbers with the merit of unpredictability relative to pseudorandom numbers generated by a computing process, especially for the lasers with external optical feedback. Here, we report the first spontaneous chaotic microlaser due to the interaction of nearly degenerate modes. The circular-side hexagonal microlaser is designed and demonstrated with adjusted mode intervals in the order of GHz for the fundamental and the first order transverse modes. Four modes including degenerate modes with strong mode beating will result in chaos. True random numbers at 10Gb/s is obtained from the laser output power with a high dimension of 5.46. Our finding provides a novel and easy way to create controllable and robust optical chaos for high speed random number generation, which also paves the way for the nonlinear dynamics in a solitary laser.
