Outline of Final Research Achievements

We demonstrate ultra-fast random number generation based on chaotic dynamics in semiconductor lasers. We generate bandwidth-enhanced chaos with unidirectionally-coupled semiconductor lasers and use it for ultra-fast random number generation. The generated random numbers pass statistical tests of randomness. We succeed in generating random numbers at the maximum generation rate of 1.2 Tb/s. We also demonstrate random number generation using photonic integrated circuits for miniaturization.
