Abstract

The fluctuating intensity of a chaotic semiconductor laser is used for generating random sequences at rates up to 12.5Gbits/s. The conversion of the fluctuating intensity to a random bit sequence can be implemented in either software or hardware and the overall rate of generation is much faster than any previously reported random number generator based on a physical mechanism. The generator’s simplicity, robustness, and insensitivity to control parameters should enable its application to tasks of secure communication and calculation procedures requiring ultrahigh-speed generation of random bit sequences.

The fast and the random

Published 13 July 2009

The fastest known random number generator based on a physical process comes from intensity fluctuations in the light from a chaotic laser.
