Researchers from North Carolina State University have discovered a technique for controlling red light with electric fields, with possible applications in photonics. It involves layers of thin material whose refractive index changes by up to 60%. “Unfortunately, it is very difficult to tune refractive index with electric fields,” said researcher Linyou Cao. “Previous techniques could ...
