Abstract
PURPOSE: To stabilize light output by permitting a linear excitation region perpendicular to a cleavage plane not to directly wih a reflection plane, and lessening an effective band gap of the excitation region than that of the non-excitation region in the active layers present therebetween.
CONSTITUTION: After growing a N-type of Al0.3Ga0.7As layer 2, a N-type of Ga As active layer, and a N-type of Al0.3Ga0.7As layer 4 progressively on a N-type of Ga As substrate 1, about one-half side of the layer 4 is covered with a Si3N4 film 5, and in the exposed region is formed a Zn diffusion region 6 entered into the layer 2. On the front of the regin 6 is then formed a Zn-implanted region 7 having a hole density of about 5×1018/cm3 to promote the laser oscillation. In this manner, the linear region 10 between both regions 4 and 6 is made of a laser oscillation region, and in its end is formed a non-excitation region 12 adjacent to the reflection plane 9. In this constitution, the effective band gap of the region 10 is lessened than that of the region 12.
