摘要：

We show that a solitarily-stable remote semiconductor laser can be driven into a chaotic state synchronized with the chaotic dynamics of a local master laser. The master laser, which is also solitarily stable, acquires its own chaotic dynamics when laterally coupled with other semiconductor lasers. Synchronization between the chaotic states of two remotely located lasers is robust for a wide range of parameter values. Transients towards synchronization take place within a time of the order of 10 ns.
