论文摘要
我们提出了一种基于激光模式跳跃的快速随机数生成的简单且全光的方法。通过定期重新启动在双态状态下工作的两种模式激光器，由于自发发射噪声，可以生成随机数流。为了验证这种方法的可行性，我们使用具有两种极化模式的常见垂直腔表面发射激光（VCSEL）进行理论模拟。数值结果表明，可以通过经过验证的随机性连续获得快速2.5 GB/s随机数流。由于其简单且全照明结构，该方案为随机数发生器提供了完全单片的解决方案。
We propose a simple and all-optical method for fast random number generation based on the laser mode hopping. Through periodically restarting a two-mode laser operating in the bistable state, a random number stream can be generated due to the spontaneous emission noise. To validate the feasibility of this method, we perform a theoretical simulation using the common vertical-cavity surface-emitting laser (VCSEL) with two polarization modes. Numerical results demonstrate that fast 2.5 Gb/s random number streams can be continuously obtained with verified randomness. This scheme provide a fully monolithic solution for random number generator, due to its simple and all-optical structure.
