World's Smallest Laser Could Help Make Faster CPUs

Aug-17-09 Instead of photons, the laser (actually, called a spaser technically) uses plasmons, a particle only 44 nanometers across. It could push CPUs' speeds to hundreds of terahertz, according to Mark Stockman, professor of physics at Georgia State:

The spaser works about a thousand times faster than the fastest transistor, while having the same nanoscale size. This opens up the possibility to build ultrafast amplifiers, logic elements, and microprocessors working about a thousand times faster than conventional silicon-based microprocessors.
