Abstract :
We demonstrate experimentally and theoretically the existence of slow chaotic spiking sequences in the dynamics of semiconductor devices (lasers and LED) with ac-coupled optoelectronic feedback. We eventually show that this regime is the result of an incomplete homoclinic scenario to a saddle-focus, where an exact homoclinic connection does not occur. The synchronization scenarios have been fully investigated.
