英文摘要 | PURPOSE:To facilitate an injection of a current, to make it possible to make low an oscillation threshold current value and to manufacture a semiconductor laser, which is suitable as a parallel integrated light source for optical information processing use, by a method wherein a laser main body part, which is provided with a first conductivity type clad layer, an active layer and a second conductivity type clad layer, an electrode part and an electrode mounting pattern part are provided on an semi- insulating semiconductor substrate and the pattern part is provided with a vacancy for isolating the second conductivity type clad layer from the first semiconductivity type clad layer by the side of the active layer. CONSTITUTION:A second conductivity type clad layer 13 on an active layer 12 is pushed out in the horizontal direction and an electrode mounting pattern part 15 having a pore 14 is provided by the side of the layer 12, whereby problems, such as the difficulty of the formation of electrodes, an increase in a contact resistance to the electrodes and the like, can be improved. Moreover, as the sectional area of a current path can effectively be made large, the resistance of the parts of the clad layers can also be reduced. Moreover, as a current is made to flow in parallel to a film, the problem of the discontinuity of a heteroband can also be avoided. |
