Abstract

We propose a scheme of all-optical random number generator (RNG), which consists of an ultra-wide bandwidth (UWB) chaotic laser, an all-optical sampler and an all-optical comparator. Free from the electric-device bandwidth, it can generate 10Gbit/s random numbers in our simulation. The high-speed bit sequences can pass standard statistical tests for randomness after all-optical exclusive-or (XOR) operation.

摘要

我们提出了一种全光随机数发生器（RNG）方案，该方案由一个超宽带宽（UWB）混沌激光器、一个全光采样器和一个全光比较器组成。由于不受电子器件带宽的限制，在我们的模拟中它能够生成10Gbit/s的随机数。高速比特序列在经过全光异或（XOR）操作后能够通过标准的随机性统计测试。
