Stanford University researchers devise an algorithm to design and build a prism-like silicon structure able to bend light at right angles-- an "optical link" for the building of the super-fast light-based computers of the future.
As the researchers put it, the optical link is a tiny slice of silicon etched with a barcode-style pattern. Much like a tiny prism the link splits light into 2 different wavelengths (or colours) at right angles to the input, forming a "T" shape.
Allowing the creation of such a structure is the algorithm, which automated the design process behind such a "previously unimaginable" nanoscale structure, one taking advantage of the differences in the speed of light as it passes from from air and silicon.
