Abstract

In the field of Nonlinear Dynamics the investigation of spatiotemporal phenomena, where a different number of spatial degrees of freedom can be involved, has recently gained considerable interest. The semiconductor laser in a T-shaped external cavity is a good candidate to study spatiotemporal chaos, because delay systems can be regarded as systems with one spatial degree of freedom along the cavity, as was demonstrated by Arecchi.¹ We in fact have been able to demonstrate the transition from temporal to spatiotemporal chaos in our delay system.
