Abstract:

We apply a dynamic (1+2)-dimensional traveling wave model and a corresponding parallel optoelectronic solver for simulations of broad-area semiconductor lasers. To avoid a significant slow-down of the numerical simulations in the presence of an external cavity, we perform a time-efficient modeling of the optical feedback. Finally, we present several simulated examples of parasitic optical feedback or an intended beam shaping by a specially designed external cavity.
