IBM makes supercomputer breakthrough
Electricity into light
IBM has moved a step closer to creating a supercomputer on a single chip after its scientists have managed to convert electrical signals into light pulses.
According to Optics Express, IBM has created electro-optic modulators 100 to 1,000 times smaller than comparable silicon photonics modulators. These are small enough to fit on a processor chip, and will enable processor cores to be connected by light instead of wires. It removes the problems of high energy consumption and heat generated by multi-core chips.
Big Blue describes the breakthrough as a "milestone" in its quest to connect hundreds or thousands of processing cores on a tiny chip.
