英文摘要	PURPOSE:To prevent degradation of performance characteristics due to useless entrappment or reflection of light in a bent activation layer by a method wherein an activation layer is provided with a flat structure in a laser device of a hybrid structure wherein a refractive index guide and gain guide are combined. CONSTITUTION:The surface of a semiconductor substrate 21 is formed flat, whereon a first clad layer 22, activation layer 23 are formed, also flat. On the activation layer 23, a light-absorbing resion 35 is selectively formed, for the construction of a refractive index guide. A second clad layer 24 is formed to fill the light-absorbing region 35, whereafter a current-constricting region 27 is formed, by ion implantation, to serve as a gain guide structure. In this way, by building activation layers flat and free of curvature across the entire region along the length of the hybrid structure, degradation of performance characteristics is prevented that may otherwise be produced due to useless light entrapment.
