Penn engineers efficiently 'mix' light at the nanoscale
University Park PA (SPX) Nov 17, 2014
The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but the fundamentals of computation, mixing two inputs into a single output, currently require too much space and power when done with light. Researchers at the University of Pennsylvania have engineered a nanowire system that could pave the way for this ability, combining two light waves to produce ... read more
