Ultra high speed random number generation based on a chaotic semiconductor laser 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 uctuating 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 ultra high speed generation of random bit sequences. Phase coherence in coupled chaotic semiconductor lasers Semiconductor lasers with optical feedback have chaotically pulsating output behavior. When two similar chaotic lasers are optically coupled, they can become synchronized in their optical fluctuations. Here we show that the synchronization is not only in the amplitude and in the timing of the pulses but that the short pulses are also phase coherent with each other. This is true even when the lasers are separated by distances much larger than their coherence length.
