No, that's not a barcode you're looking at -- instead, it's the likely future of computing. Stanford University researchers have developed an optical link that uses silicon strips to bend light at right angles, which future processors will likely need to transmit data at super-fast speeds. The key, as you might have gathered, is the series of gaps. When light hits the device, the combination of those gaps and silicon sends different wavelengths left and right. You're not limited to specific light bands or directions, either; you can use an algorithm to design the link you need within a matter of minutes.
