IBM and DARPA Create A New Optical Link For Super Computers

The supercomputers of tomorrow will be capable of feats never thought possible: model global climate change, run molecular-level simulations of entire microscopic cells, design nanostructures and more, all very quickly. In fact, thee team behind these exascale computers are planning to break previous the energy efficiency record by over half.

They plan to do this, "By combining innovative circuits in IBM's 32-nanometer silicon-on-insulator complementary metal-oxide-semiconductor (SOI CMOS) technology with advanced vertical cavity surface emitting lasers (VCSELs) and photodetectors fabricated by Sumitomo Electric Device Innovations USA (formerly Emcore)," says Jonathan E. Proesel, an IBM team member. They have essentially made an optical communication link operating at 25 gigabits per second using just 24 milliwatts of total wall-plug power, or 1 pJ/bit.
