We use the traveling wave model for simulating and analyzing nonlinear dynamics of complex semiconductor ring
laser devices. This modeling allows to consider temporal-spatial distributions of the counter-propagating slowly
varying optical fields and the carriers, what can be important when studying non-homogeneous ring cavities,
propagation of short pulses or fast switching. By performing numerical integration of the model equations we
observe several dynamic regimes as well as transitions between them. The computation of ring cavity modes
explains some peculiarities of these regimes.
