25 Gb/s VCSEL Chip developed by NEC
Who says we do not know where we're going: from the press release :"The largest issue in current supercomputer performance is the data transmission speed among LSI chips or boards in comparison to the data processing speed in LSI chips. Replacing the electrical signals with optical signals is a logical move as optical interconnection enables high-speed operation and high-density mounting. Among semiconductor lasers, VCSEL is advantageous since it can operate at low power and carry out high-density integration. Therefore, the features of the newly developed VCSEL are very beneficial to next-generation supercomputing systems, in which high-density optical interconnection will be carried out between CPUs and memories". I would say our lab is eminently positioned to take advantage of that fact !
