Switching nanolight on and off
E-Mail IMAGE: An optically excited gas of electronic carriers confined to the planes of the layered van-der Waals semiconductor tungsten diselenide is shown. The consequent hyperbolic response permits passage of nanolight. view more Credit: Ella Maru Studio A team of researchers led by Columbia University has developed a unique platform to program a layered crystal, producing imaging capabilities beyond common limits on demand. The discovery is an important step toward control of nanolight, which is light that can access the smallest length scales imaginable. The work also provides...
