英文摘要 | PURPOSE:To realize a simple wafer process in which a crystal growth process is carried out only once and the diffusion of impurities and the formation of an insulating film are not executed by a method wherein many oblique grooves are previously provided to a substrate possessed of a plane (100) as a primary face so as to make a plane (-1-1-1) and a (-l-1-1) plane exposed. CONSTITUTION:Oblique grooves are previously provided to a P-type GaAs substrate 2a possessed of a plane (100) as a primary face so as to make a plane (100) and a plane (-1-1-1) exposed. A boundary line 12 of a PN junction is a natural diffusion line of Zinc. Provided that a P-type AlxGa1-xAs clad layer 3 is doped with zinc twice as high in concentration as an N-type AlxGa1-xAs clad layer 5, a doping boundary is made to move as Zinc is diffused by heat during the growth of crystal. At this point, Zinc is diffused faster in a direction (1111) than in a direction (100), so that a PN junction is located inside an active layer 4 on a plane (100) but the diffusion of zinc is made to proceed on a plane (111) until it reaches to the N-type AlxGa1-xAs clad layer 5, and a PN junction is located inside the N-type AlxGa1-xAs clad layer 5. In this case, As the PN junction located inside the active layer 4 is lower than that located inside the clad layer 5 in potential, a laser oscillation takes place in this part but not in the other part. As the active layer 4 is located close to the P-type GaAs substrate 2a in a groove, laser oscillation is prevented from occurring there due to a large loss induced by absorption. |
