Coupled complex Ginzburg-Landau equations describe generic features of the
dynamics of coupled fields when they are close to a Hopf bifurcation leadin
g to nonlinear oscillations. We study numerically this set of equations and
find, within a particular range of parameters, the presence of uniformly p
ropagating localized objects behaving as coherent structures. Some of these
localized objects are interpreted in terms of an analytical ansatz. (C) 20
