Abstract

PURPOSE:To enable various laser elements having different oscillation wavelengths to be integrated without incorporating diffraction gratings, by providing a plurality of semiconductor laser elements with quantum well layers as active layers thereof while differentiating their compositions of well layers from each other among the various laser elements. CONSTITUTION:In a semiconductor laser array device having two or more semiconductor laser elements formed on one and the same semiconductor substrate and capable of being driven independently from each other, active layers 104-107 of a plurality of semicon ductor laser elements are provided by quantum well layers while differentiating compositions of well layers thereof from each other among the various semiconductor laser elements. In this manner, it is possible to provide a multi-wavelength integrated semiconductor laser without the need of incorporating diffraction gratings but by such simple construction as to provide the various semiconductor laser elements with quantum well active layers whose compositions of well layers are different from each other among these laser elements.
