摘要:

提出了一种基于激光跳模的全光快速随机数产生方法。通过周期性地重新启动工作在双稳态的双模激光器,由于自发发射噪声,可以产生随机数流。为了验证这种方法的可行性,我们进行了理论模拟,使用普通的垂直腔面发射激光器(VCSEL)的两个偏振模式。数值结果表明,该方法可以连续地获得快速的2.5Gb/s随机数码流,并具有一定的随机性。该方案由于结构简单、全光,为随机数发生器提供了一种全单片化的解决方案。

英文摘要:

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.
