Patent ID: 7630594

Claim:
An optical interconnection module, used to transmit an optical signal, comprising: at least one optoelectronic element, having an optical transmission port for transmitting the optical signal, and at least one first alignment element adjacent to the optical transmission port; a substrate, having an optical waveguide, at least one opening disposed on the surface of the substrate and connected to the optical waveguide, and at least one second alignment element adjacent to the port, wherein the optical signal is transmitted between the opening and the optical waveguide; and at least one optical coupling element, comprising an optical transmitting portion corresponding to the optical transmission port and the opening, at least one first matching element corresponding to the first alignment element, and at least one second matching element corresponding to the second alignment element, the first matching element and the second matching element being integrally formed from the two sides of the optical coupling element, wherein the first matching element is engaged with the first alignment element, the second matching element is engaged with the second alignment element, so as to make the optical signal transmitted among the optical transmission port, the optical transmitting portion, the opening, and the optical waveguide, and the optical transmitting portion is a double-convex lens, protruded from the two sides of the optical coupling element to form a lens shape.
