Optical transistor will be faster than CMOS devices

by Richard Wilson - Electronics Weekly, Aug. 06, 2015 – 

Researchers in the US have demonstrated what is in effect an 'optical transistor' which can modulate light, as in optical fibre communications, at terahertz frequencies.

The team at Purdue University claim that the so-called "plasmonic oxide material" could make possible devices for optical communications that are at least 10 times faster than conventional technologies.
