Summary:
We experimentally demonstrate amplification of intrinsic microscopic noises by the dynamical instabilities in high dimensional chaotic laser systems, semiconductor lasers with delayed optical feedback. Then we discuss nondeterministic random bit generation using chaotic lasers, and show that the relation between the entropy of the bit sequences obtained by using chaotic lasers and the rates of the bit extraction can be understood in terms of the effect of the noise amplification.
