The spatially inhomogeneous distribution of the light intensity and of the excitation density is investigated for systems showing cavityless optical bistability due to increasing absorption. The formation and motion of spatial kink structures is analyzed in detail within a rate-equation approach. Analytical estimates for the kink formation process are presented and compared to numerical results.
