Narrowing of the far field in spatially modulated edge-emitting broad area semiconductor amplifiers
2015, Radziunas, Mindaugas, Herrero, Ramon, Botey, Muriel, Staliunas, Kestutis
We perform a detailed theoretical analysis of the far field narrowing in broad-area edgeemitting semiconductor amplifiers that are electrically injected through the 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.
