基于互注入半导体激光器的混沌输出产生17.5Gbit/s随机码
17.5 Gbit/s random bit generation using chaotic output signal of mutually coupled semiconductor lasers
摘要
Abstract
Based on two mutually coupled semiconductor lasers linked by fiber,a chaotic seed signal with a 10 GHz ultra-broadband is obtained experimentally.Adopting an 8-bit analog-to-digital converter,the seed signal is converted into a binary bit stream.By an exclusive-OR operation and the most significant bit rejection,a random bit sequence at a rate up to 17.5 Gbit/s,which has passed both the National Institute of Standard and Technology statistical test and the Diehard test,is obtained.关键词
