We study a possibility of implementing a single-mode DFB heterolaser with inclined (with respect to the surface of the structure) output of the generated radiation. We find the periodic dielectric structure shape that makes it possible to realize the distributed feedback for wavebeams propagating along the structure and, at the same time, to ensure the output of up to 70% of the generated radiation power in the inclined direction. Within the framework of the semiclassical quasi-optical model, the possibility of stationary lasing regimes is shown for finite lateral dimensions of the Bragg structure. Keywords: heterolaser, Bragg structures, distributed feedback, radiation output.
