Researchers from the Swiss Federal Institute of Technology have developed an optical transistor that uses one laser beam to control another, potentially forming the foundation for a new generation of ultrafast light-based computers. The researchers say laser-based transistors can be used to create light-based computers, which would use optical fibers to carry light.
