| dc.description.abstract | We perform a detailed theoretical analysis of the far-field narrowing in broad-area edge-emitting semiconductor amplifiers that are electrically injected through contacts periodically modulated in both longitudinal and transverse directions. The beam propagation properties within the semiconductor amplifier are explored by a (1 + 2)-dimensional traveling wave model and its coupled-mode approximation. Assuming a weak field regime, we analyze the impact of different parameters and modulation geometry on the narrowing of the principal far-field component. |
