Abstract:
An optical wiring device, comprising:a first substrate having a first surface and a second surface on an opposite side of the first surface, and having a hole through the first substrate between the first and second surfaces; an integrated circuit disposed on the first surface of the first substrate; a photoelectric conversion element provided on the first surface of the first substrate and configured to convert between electrical signals and optical signals; an optical terminal disposed in contact with the hole on a side of the second surface of the first substrate; and a second substrate having an optical wiring, and being attached to the first substrate with the optical terminal therebetween, said optical wiring running within said second substrate, wherein the second substrate has a concave portion, and the optical terminal has a curved plane in contact with the concave portion of the second substrate so as to be optically coupled to the optical wiring, and wherein the electrical signals are transmitted between the photoelectric conversion element and the integrated circuit, and the optical signals are transmitted between the photoelectric conversion element and the optical wiring through the optical terminal.
