IBM research team has developed a new kind of optical modulator that converts a digital electrical signal carried on a wire into a series of light pulses which can be carried on a silicon nanophotonic waveguide. What essentially this means is that going forward, a series of multi-core computer chips could be connected via these modulators.
The new technology aims to enable a power-efficient method to connect hundreds or thousands of cores together on a tiny chip by eliminating the wires required to connect them. Using light instead of wires to send information between the cores can be 100 times faster and use 10 times less power than wires.
How it works, check out the video:
