Optical link

Stanford engineers have designed and built a prism-like device that can split a beam of light and bend it at right angles a further step in their aim of developing nanophotonics and optical computing. The full paper is available here describing the optical link, a slice of silicon etched with a grating to split two different wavelengths of light at right angles separating O-band (1300 nm) and C-band (1550 nm) light into separate waveguides
