英文摘要 | PURPOSE:To obtain a laser device, an astigmatism and noises therefrom are small and which is suitable for a light source for an optical disk, by simultaneously forming refractive-index waveguide structure and gain waveguide structure in the direction of a resonator and independently selecting structural parameters determining the effective refractive-index difference of a refractive-index waveguide section and the gain distribution of a gain waveguide section. CONSTITUTION:An n type Ga0.55Al0.45As clad layer 2, an un-doped Ga0.85Al0.15 As active layer 3 and a p type Ga0.65Al0.35As optical guide layer 4 are laminated on an n type GaAs substrate 1 and grown in a liquid phase in an epitaxial manner, and a latticed optical guide with striped projecting sections 5 and flat sections 6 is formed on the surface of the layer 4 through etching by a phosphoric acid group etchant while being covered with a resist mask. A p type Ga0.55Al0.45As clad layer 7 and a p type GaAs contact layer 8 are grown on the latticed optical guide through a molecular-beam epitaxial method, the layer 8 is changed into a plurality of striped shapes through etching, and sections among the striped layers 8 are buried with oxide films 9. Metallic electrodes 11 and 12 are each applied on the films 9 and the back of the substrate |
