Abstract: A model for calculating the spatial distribution and decay time of electromagnetic modes in laser structures with a dielectric or metal diffraction grating parallel to the active layer is developed. Self-consistent calculation of the efficiency of vertical emission is performed taking into account backscattering and the interaction of scattered waves with substrate modes. The possibility of longitudinal mode selection as a result of the frequency dependence of the decay time without the use of distributed feedback is discussed.
