1. An optical element device comprising:
a light emitting element; and
a substrate mounting the light emitting element thereon and having an optical path transforming structure,
wherein an integral semiconductor body comprises each of the light emitting element and the substrate, whereby a surface of the light emitting element and a surface of the substrate are attached to each other,
wherein the optical path transforming structure is configured to change a light proceeding direction to couple light from the light emitting element with a light receiving element, and
wherein the substrate comprises a GaAs layer and a semiconductor layer, and the light emitting element is formed on the GaAs layer and the optical path transforming structure is formed on the semiconductor layer.
