混沌半导体激光器的随机位产生(RBG)因其在保密通信和高速数值模拟中的潜在应用而受到广泛的研究。这一领域的研究主要集中在提高随机比特生成器的生成率和紧凑性上。在本文中，我们用延迟光反馈的单个混沌激光器实验证明了快速RBG的两个区域的存在：第一个区域是基于每个随机样本中包含的所有最小熵的提取，第二个区域是通过从每个变量中提取55比特来提高生成速率的可能性。
Random bit generation (RBG) with chaotic semiconductor lasers has been extensively studied because of its potential applications in secure communications and high-speed numerical simulations. Researchers in this field have mainly focused on the improvement of the generation rate and the compactness of the random bit generators. In this paper, we experimentally demonstrate the existence of two regimes of fast RBG using a single chaotic laser subjected to delayed optical feedback: the first one is based on the extraction of all min-entropy contained in each random sample, and the second one is to demonstrate a possibility of increasing the generation rate by extracting 55 bits from each variable.
