IBM continues to advance towards the technology of using light to carry data quickly "among cores within a microprocessor, taking the company closer to developing a chip that may one day run notebooks with the horsepower of today's supercomputers."
Communications between processor cores handled through copper wire that moves electrical impulses. IBM hopes to eventually replace that wire with a light beam that follows a tiny silicon its destination. Light carries more data in the same amount of time as copper by being 100 times faster."
"But the bigger problem in eventually taking light-driven chips to market will be in manufacturing... Introducing light technology means new equipment and a whole new way of production. Such a major transformation will take time."
