Abstract:
1. A semiconductor submodule comprising: a first substrate having at least one hole, at least one optical semiconductor device disposed such that light passes through said hole, and at least one high-speed electrical signal transmission path electrically connected with said optical semiconductor device; a second substrate having a semiconductor device for driving said optical semiconductor device, at least one high-speed electrical signal transmission path electrically connected with said semiconductor device, and an electrical connector having the function of inputting or outputting a high-speed electrical signal with respect to the outside, with the connector being connected with said high-speed electrical signal transmission path; wherein a terminal end of each of said high-speed electrical signal transmission paths is connected such that an end face said first substrate has a mechanism for allowing it to be folded toward the opposite side to the surface thereof on which said optical semiconductor device is mounted, either of said end faces opposite to each other serving as a fulcrum of said mechanism; and a cap structure for hermetically enclosing said optical semiconductor device is provided on said first substrate on which said optical semiconductor device is mounted and at least one micro lens or a transparent thin plate having an optical axis extending along the center axis of said hole and having a surface area smaller than the surface area of said first substrate is provided on a back surface side of said first substrate on which said optical semiconductor device is mounted.
