The experimentaldevices are semiconductor lasers with ultra-short optical feedback, which is inte-grated on the same chip as the laser. By adding sections with different functionality,which can be individually biased with a direct current, all feedback parameters canbe adjusted. A wide variety of dynamical scenarios can be prepared with such amultisection laser. When the devices are operated near bifurcations, the dynamicscan be reduced to the same mathematical models valid for the description of manyseemingly distinct physical systems.
