英文摘要 | PURPOSE:To obtain a semiconductor laser device having a low operation current and less astigmatism by forming a current blocking layer on a substrate, forming a stripelike groove on the layer, and sequentially forming an optical guide layer, an active layer and a clad layer thereon. CONSTITUTION:A Zn-doped P-type AlGaAs clad layer 2, an N-type GaAs current blocking layer 3 and a P-type GaAs current blocking layer 4 are sequentially grown by an MOCVD method on a P-type GaAs substrate 1, and only the layers 3, 4 are formed with stripelike grooves. Then, an N-type AlGaAs layer 5, an N-type AlGaAs clad layer 8 and an N-type GaAs contact layer 9 are sequentially grown by an MOCVD method. In case of the second MOCVD method, Zn dopant in the layer 2 is diffused in the layer 5 to invert only the stripelike groove part to P-type to form a P-type AlGaAs optical guide layer 6. Thus, a current passage becomes only the stripelike groove, thereby eliminating a reactive current path to the other part. |
