英文摘要PURPOSE:To facilitate the oscillation of a fundamental mode and to turn out a high power by performing a mesa etching to the depth penetrating an active layer of a four-layer structure section having a light guiding layer and a carrier confinement layer. CONSTITUTION:A positive current is applied to a P-type electrode, a negative current is applied to an N-type electrode, a carrier is injected into an active layer 14 and a luminescence is obtained by recombination. The injected carrier is confined by the semiconductor layers 13 and 15 located in the vicinity of the active layer. When a gain surpasses a loss with a sufficient application of current, a laser beam is generated from the active layer 14. This beam oozes out to a beam guide layer 13 and is guided by a beam confinement layer 12 having a low refractive index and a beam- carrier confinement layer 15. As the thickness of a central part 20 of a guide layer 13 differs from that of its outside, the lateral refractive index distribution becomes larger as compared with the central part. In other words, it means that a beam waveguide mechanism is fabricated in a luminous region and the fundamental mode confined within said region is oscillated to the lateral direction, too. The fact that the lateral direction of the active layer has a mesa etching in a striped form shows that the diffusion of the carrier is limited within the mesa-type protruded section only.
