Abstract
The optical module of the invention includes: a first substrate; a vertical-cavity surface-emitting laser including an upper surface, a bottom surface and a semiconductor multi-layered structure including at least a light-emitting layer, the vertical-cavity surface-emitting laser being supported on the first substrate; an electrode structure electrically connected with the bottom surface of the vertical-cavity surface-emitting laser, the electrode structure being supported on the first substrate; and a second substrate including a first bump and a second bump. In the optical module, an upper surface of the electrode structure and the upper surface of the vertical-cavity surface-emitting laser jut out from the first substrate. The second substrate is positioned with respect to the first substrate so that the first bump and the second bump come into contact with an upper surface of the electrode structure and the upper surface of the vertical-cavity surface-emitting laser, respectively.
