Samsung patents light connector using a bridge to guide fiber

Samsung has filed a patent for a device that connects a light source to an optical fiber using a specific arrangement of components. The design uses an "optical bridge" and two other optical elements to guide light from the source into the fiber in a straight line.

Why it mattersThis is a technical improvement for how light is routed in electronic devices, which could help maintain consistent signal quality in high-speed data connections.

In the filing’s own words

Provided is a coupling device including a substrate including a light source, the substrate extending in a first direction and a second direction, and having a thickness in a third direction, a first coupling unit, and a second coupling unit, wherein the first coupling unit includes an optical bridge spaced apart from the substrate in the third direction, and a first optical element adjacent to the optical bridge in the first direction, wherein the second coupling unit includes a second optical element between the substrate and the optical bridge, and an optical fiber spaced apart from the first optical element in the first direction, and wherein the light source is configured to output light to be sequentially incident on the second optical element, the optical bridge, the first optical element, and the optical fiber.

What exactly they claim (claim 1)

1. A coupling device comprising: a substrate comprising a light source, the substrate extending in a first direction and a second direction, and having a thickness in a third direction; a first coupling unit comprising: an optical bridge spaced apart from the substrate in the third direction; and a first optical element adjacent to the optical bridge in the first direction; and a second coupling unit comprising: a second optical element between the substrate and the optical bridge; and an optical fiber spaced apart from the first optical element in the first direction, wherein the light source is configured to output light to be sequentially incident on the second optical element, the optical bridge, the first optical element, and the optical fiber.
