Abstract: PURPOSE: To provide a semiconductor and a production method with which the layer of lump-shaped active materials are not used for achieving satisfactory performance as regards absolute and differentiated gains. CONSTITUTION: Optical feedback is provided by a grid 2 of passive semiconductor materials, an active medium exists only in the groove of grid 2, and the wire and barrier of quantum wire structure are formed by discontinuous layers 5 of optically active materials separated by an optically passive material layer 6. An optical confinement layer 7 is provided on the grid 2 and the multiplex quantum wire structure. Further, the production method for the semiconductor laser is provided as well.
