Light-based 'Metatronics' chip melts minds, not copper

Engineers on the College of Pennsylvania have flipped the change on a brand new sort of pc circuit. In contrast to typical silicon, the brand new chip makes use of mild — not electrical energy — to carry out its logic. By creating an array of nano-rods, mild-move may be handled like voltage and present. These rods can then be configured to emulate electrical elements corresponding to resistors, inductors and capacitors. The advantages of the so-referred to as “metatronic” system can be smaller, quicker and extra environment friendly pc chips, which is clearly a welcome prospect. One other curious property the staff found, is what it calls “stereo-circuitry.” Successfully one set of nano-rods can act as two totally different circuits, relying on the aircraft of the sector. This implies your CPU might turn into a GPU simply by altering the sign. We will not converse for the sunshine itself, however our minds are definitely bent.
