Abstract
An optical transmission apparatus comprising a first gradient index lens, an optical receiver, and a second gradient index lens. The first gradient index lens is connected to an end of an optical transmission line. The optical receiver receives light and is provided to an electronic device. The second gradient index lens is arranged between the first gradient index lens and the optical receiver.
Claims19
An optical transmission apparatus comprising:
- a first gradient index lens connected to an end of an optical transmission line;
- an optical receiver that receives light, the optical receiver being provided to an electronic device, the electronic device being mounted on an intermediate substrate, the intermediate substrate being mounted on a wiring substrate, and the intermediate substrate having a through-hole penetrating therethrough in a stacking direction with respect to the wiring substrate;
- a second gradient index lens arranged between the first gradient index lens and the optical receiver, and at least partly arranged in the through-hole of the intermediate substrate;
- and
- a stopper that positions the second gradient index lens with respect to the optical receiver, the stopper being arranged at an end of the through-hole of the intermediate substrate, the end being adjacent to the electronic device,
- wherein the first gradient index lens and the optical transmission line are arranged in a depression formed in a surface of the wiring substrate that faces the intermediate substrate.
