Researchers from North Carolina State University have discovered a technique for controlling light with electric fields. “Our method is similar to the technique used to provide the computing capabilities of computers,” says Linyou Cao, an assistant professor of materials science and engineering at NC State. “In computers, an electric field is used to turn electric current on or off, which corresponds to logic 1 and logic 0, the basis of binary code. With this new discovery, a light may be controlled to be strong or weak, spread or focused, pointing one direction or others by an electric field...
