Abstract
A multi-wavelength semiconductor laser device includes a plate stem; a prism shaped submount with a bottom face on a face of the stem; laser diodes having emission wavelengths different from each other are mounted on lateral sides of the submount so that their respective emission points are positioned at substantially the same distance from a center axis of the stem; and lead pins penetrating the stem are located along and opposite edge lines between adjacent pairs of the lateral sides of the submount.
