英文摘要 | PURPOSE:To improve the yield of manufacturing an array element having a plurality of semiconductor lasers including uniform wavelength intervals by inclining the linear regions of stripelike waveguides of lasers with respect to the forming direction of a diffraction grating, and forming them nonparallel to each other. CONSTITUTION:A diffraction grating pattern is written on a p-type InGaAsP optical guide layer 4, and formed in an uneven state by etching to form the periods of diffraction gratings on the entire surface of a substrate in the same direction such as in a direction . Then, a p-type InP clad layer 5 and a p-type InGaAsP electrode layer 6 are continuously grown. Thereafter, a thin SiO2 film is formed on the entire surface, and thin films are formed in a plurality of stripes along a direction by photoetching. Here, angles formed between the stripes (a)-(d) corresponding to lasers La, Lb, Lc, Ld and a plane are respectively set to about 3.57, 2.91, 2.06, 0.0 deg. With the thin films as masks it is etched until it reaches the substrate 1 to form a laminate of an inverted mesa shape. |
