Abstract
A semiconductor laser device includes a submount, a semiconductor laser element, and a bonding material. The semiconductor laser element includes a substrate and a layered structure, and is disposed with the layered structure facing the submount. A waveguide extending in a first direction parallel to the main surface of the substrate is formed in the layered structure. The bonding material includes an inner region bonded to the semiconductor laser element and one outer region located outward of the inner region. The one outer region is spaced apart from one side surface of the semiconductor laser element. Width A of the semiconductor laser element and width B of the one outer region in a second direction perpendicular to the first direction and parallel to the main surface of the substrate satisfy B≥A/4.
