Nano-tech advancement in light based computers

Researchers at Penn State's BioNEMS group have built a plasmonic switch.  Combined with optical transistors to make tiny optical circuits , these researchers are on the way to building the worlds first optical computers.

"Plasmonic circuits are a hybrid of electronics and photonics,'' he stated. ''They can transmit electrons and light at the same time."
