英文摘要 | PURPOSE:To prevent leakage currents, to make the greater part of injection currents to contribute to laser oscillation and to enable oscillation at low threshold currents by forming a second current constriction layer covering the side wall of a striped groove. CONSTITUTION:A first clad layer 2, an active layer 3, a second clad layer 4 and a current constriction layer 5 are shaped onto an n-type GaAs substrate 1 in succession, and a striped groove reaching up to a section in the vicinity of the active layer is formed through selective wet etching. An n-type AlxGa1-xAs layer is grown on the whole surface in an epitaxial manner, and the n-type AlxGa1-xAs layer 9 is wet-etched only by the film thickness section of the layer 9. A second current constriction layer 8 is left only on the side wall of the striped groove, and an optical guide layer 6 and a contact layer 7 are grown successively. Accordingly, the second current constriction layer 8 consisting of n-type AlxGa1-xAs is shaped onto the side wall of the striped groove, thus bringing the optical guide layer 6 into contact with the second clad layer 4 only on the bottom of the striped groove. |
