英文摘要PURPOSE:To form a stripe having a plurality of stages by single photoresist processing by forming a heterogeneous layer between a region for forming difference in refractive index and a region for narrowing current and etching them with different kinds of etchant respectively. CONSTITUTION:An n-InGaP buffer layer 12, an n-In0.5(Ga0.3Al0.7)0.5P clad layer 13, an InGaP active layer 14, a p-In0.5(Ga0.3Al0.7)0.5P clad layer 15, a p-InGaP etching stop layer 16, a p-In0.5(Ga0.3Al0.7)0.5P clad layer 17, an n-InGaP heterogeneous layer 18 and an n-GaAs current preventing layer 19 are formed on an n- GaAs substrate 1 A resist mask 20 having a stripe opening is formed on the layer 19. Then SH etching solution is used to etch the layer 19 in stripes. Then etchant of hydrogen bromide is used to etch the layer 18 and hot sulfuric acid is used to etch the layer 17. A p-In0.5(Ga0.5al0.5)0.5P coating layer 21, a p-In0.5(Ga0.3 Al0.7)0.5P coating layer 22, a p-InGaP intermediate band gap layer 23, a p-GaAs contact layer 24 and electrodes 25, 26 are formed.
