Abstract
An object is to provide a multi-wavelength integrated semiconductor laser device which can reduce variations in emission point distance, can be formed by simplified manufacturing processes, and can provide improve electric characteristics. A first semiconductor laser elementhaving an active layer ALfor emitting a laser beam of a first wavelength from its light-emitting point Xand a second semiconductor laser elementhaving an active layer ALfor emitting a laser beam of a second wavelength from its light-emitting point Xare bonded to each other via an adhesive layer MC made of metal. At least either one of the semiconductor laser elements has a ridge waveguide made of an n-type semiconductor. The semiconductor laser elementsandare bonded via the metal adhesive layer MC at the sides of their respective p-type semiconductors. A submount SUB is bonded to the first semiconductor laser elementvia metal at a side where its ridge waveguide is formed.
