英文摘要 | PURPOSE:To enable single mode oscillation, in which the shape of a buried active layer is formed in a vertical bilateral symmetrical shape by semiconductor laser structure with the buried active layer, a section thereof takes a convex lens shape, and to obtain a laser spot close to a point. CONSTITUTION:Manufacture of the titled device is as follows. A striped groove 32 is formed onto epitaxial layers 21, 22, 23 grown onto an n-InP substrate 21 in succession, and a layer which must function as a clad layer 24 is grown onto the groove so that a sectional shape in the groove 32 takes a concave surface form. A layer which must function as the active layer 25 is grown onto the layer which must function as the clad layer 24, a protective mask 33 narrower than stripe width is formed at the center of the stripe section of the surface, and the section of the active layer 25 is formed to a convex lens shape through etching from the upper surface of the mask. The film 33 is removed through etching, a clad layer 26 and a constricted current layer 27 are grown through a liquid epitaxial growth method again, cadmium (Cd) is diffused and p-type region is formed, a p-type electrode and an n-type electrode are formed, and the laser element is completed. |
