Engineers discover a new gatekeeper for light Buffalo NY (SPX) May 30, 2016 - Imagine a device that is selectively transparent to various wavelengths of light at one moment, and opaque to them the next, following a minute adjustment. Such a gatekeeper would enable powerful and unique capabilities in a wide range of electronic, optical and other applications, including those that rely on transistors or other components that switch on and off. In a paper in the journa ... more
