英文摘要PURPOSE:To perform the adjustment of an emission angle of a laser beam without using a lens by providing a waveguide layer of refractive index distribution type oppositely to an emission plane of a laser element including an edge plane of an active layer which will become an edge plane of a resonator so as to change the refractive index outward in order. CONSTITUTION:On a substrate 11, a lower cladding layer 13, an active layer 15 and an upper cladding layer 17 are laminated to compose a double hetero structure and one edge part of the layers 13-15 is etched by directional chemical etching in vertical direction to the active layer 15 and down to a depth reaching the substrate 11, thereby forming a cavity 3 Next, a refractive index distribution type waveguide layer 33 is arranged in this cavity 3 This waveguide layer 33 is arranged oppositely to an emission plane of a laser element 29 and the refractive index is changed in order from the center 33a of the waveguide layer 33 opposite to the center of an edge plane 35 of a resonator in the emission plane toward the outsides 33b and 33c.
