Bringing Fiber Optics to Computer Chips
More and more, fiber optic cables are being installed for carrying information across networks and across the Internet, because they are great speed and capacity. Many would like to see fiber optics enter our computers as well, but shrinking the cables has been proving difficult. Researchers at the University of Alberta though, have managed to create nano-optical cables that could enter our computer chips.
Presently copper wires are used within computer chips as interconnects, because the metal does a decent job. Optical fibers could do better, but their diameter has been limited to the micrometer range, which is too large. By turning to metamaterials however, the Alberta researchers were able to go an order of magnitude smaller, without losing data, slowing the signal, or creating heat. As you can no doubt guess, bringing fiber optics into chips would also bring significantly greater speeds and efficiencies than what we see now.
