英文摘要 | PURPOSE:To eliminate the unequal inclination of an impurity in the deviation region of the interface of an active layer by a method wherein an impurity doped in a crystal layer connected to an active layer and an active layer by a substrate side is made as the same kind of P type in a laser element which epitaxially grew multilayer crystal structure having the active layer on a P type semiconductor substrate. CONSTITUTION:A P type Ga1-yAlyAs clad layer 2' and a Ga1-xAlxAs active layer 3' doped the same impurity as that in the clad layer 2' are stacked on a P type GaAs substrate 1 for liquidus epitaxial growth. Namely, the active layer 3' is set as P type and the same kind of an impurity selected from Zn, Ge, Mg or the like is used as the impurity added to the layers 2' and 3'. In this way, unequally does not exist even if an impurity is mixed to the layer 3' from the layer 2'. After that, an N type Ga1-yAlyAs clad layer 4 and an N type GaAs cap layer 5 are stacked on the layer 3' for growth and if necessary, a current strangulation mechanism is provided. |
