| 英文摘要 | PURPOSE:To contrive to make the best use of the advantages of both of refractive index guide type oscillating parts and a gain guide type oscillating part as well as to complement the defects of both each other and to obtain a semiconductor laser, which is superior in a formation of spot light, by a method wherein a manufacturing process, wherein regions with an effective refractive index smaller than that of the luminous region are disposed on both sides of the luminous region and the refractive index type oscillating parts are constituted, and other manufacturing processes are carried out. CONSTITUTION:A first clad layer 2 consisting of an N-type AlZGa1-ZAs layer, an active layer 3 consisting of a P type or N type AlXGa1-XAs layer, a second clad layer 4 consisting of a P type AlZGa1-ZAs layer, photo absorption layers 5 consisting of N type AlYGa1-YAs layers buried in the second clad layer 4 and a P type high-impurity density cap layer 6 are provided on an N type GaAs substrate The photo absorption layers 5 are both selected their compositions in such a way that their forbidden band widths are ones smaller than that of the active layer 3 and their effective refractive indexes related with light to oscillate from the luminous region of the active layer 3 are ones lower than that of the luminous region, that is, the active layer 3. Moreover, an oscillating part, wherein both of refractive index type oscil lating parts and a gain guide type oscillating part coexist, is constituted without making uniform the width of a stripped cut-away 9, that is, the intervals between the cut-away part 9 and the photo absorption layers 5 on both sides of the cut-away part 9 in each part of the cut-away part 9. |
