Consistency and complexity in semiconductor lasers with time-delayed feedback

[出版社版]Many nonlinear dynamical systems show the consistent behavior when they are driven repeatedly with a complex signal, which is called consistency. Application of consistency to physical one-way function has been expected. In this work, we investigate the consistency of coupled semiconductor lasers with optical feedback and measure the complexity of the coupled laser system by using Lyapunov spectrum. It is found that the complexity of coupled lasers decreases suddenly when consistency is achieved
