Patent ID: 8916418

Claim:
A surface-emitting laser module comprising: a surface mining laser array, including a plurality of surface-emitting lasers, formed on a substrate, each of the surface-emitting lasers being configured to emit light perpendicular to a surface thereof; a package including a recess portion in which the substrate having the surface-emitting laser array formed thereon is arranged; and a transparent substrate arranged to cover the recess portion of the package together with the substrate having the surface-emitting laser array formed thereon located in the recess portion of the package such that the transparent substrate and the package are connected to each other on a light emitting side of the surface-emitting laser array, wherein a high reflectance region and a low reflectance region are formed within an emission region enclosed by an electrode formed on an upper part of a mesa of each of the surface-emitting lasers, the high reflectance region being formed in a central part of the emission region and the low reflectance region being formed in a peripheral part of the emission region, the central part having a reflectance higher than the peripheral part, and wherein the high reflectance region includes two different widths in two orthogonal axis directions on a surface in parallel with the upper part of the mesa, a width of the high reflectance region in one axis direction amongst the axis directions being shorter than a width of the high reflectance region in the other axis amongst the axis directions, and the transparent substrate is slanted to a surface of the substrate in the one axis direction having the shorter width.
