      ‘Exceptional’ Research: Unexpected Light Behavior May Be Harnessed to Improve Optical Communications and Sensors
      
            The NIST team directed light into an ultrathin layer of silicon nitride etched with grooves to create a diffraction grating. If the separation between the grooves and the wavelength of light is carefully chosen, the intensity of light declines much more slowly, linearly rather than exponentially.
