All this clean energy sounds very green.

optical switches have been demonstrated using terahertz and ultrafast laser pulses to control the electrical signal and enhance the switching speed to the picosecond and a few hundred femtoseconds time scale.which would increase the data transfer speed and could be used in long-distance communications from Earth into deep space.

the development of ultrafast optical electronics and the building of “optical transistors” will be made possible by the use of laser light to regulate electrical signals in the future of electronics.was able to switch a light signal optically at attosecond rates in order to achieve hitherto unreachable data transfer speeds: one quintillionth of a second is an attosecond.we present the capability of controlling the optical switching signal with complex synthesized fields of ultrashort laser pulses for data binary encoding.

the fastest semiconductor transistors in the world can operate at a speed of more than 800 gigahertz.UArizona physics postdoctoral research associate Dandan Hui and physics graduate student Husain Alqattan also contributed to the article.

This work paves the way for establishing optical switches and light-based electronics with petahertz speeds.according to Carruthers and Jacksons Data Maturity Index.
