ABSTRACT
We study the effects of delayed coupling on spatio-temporal dynamics in a locally coupled chain of identical Ginzburg-Landau oscillators. Using the biorthogonal decomposition method, we construct the phase diagrams in the parameter space of coupling and nonlinearity for various time delays. We find that the time delay reduces the dynamic complexity of chaotic states in most regions of the parameter space beyond the Benjamin-Feir (BF) instability limit. We find, however, that in regions of spatio-temporal intermittency, the time delay leads to the recurrence of states with high dynamic complexity from pattern competition. © 2000 American Institute of Physics.
