Physicists Find Right (and Left) Solution for On-Chip Optics: Nanoscale Router Converts and Directs Optical Signals Efficiently
A Harvard-led team of researchers has created a new type of nanoscale device that converts an optical signal into waves that travel along a metal surface. Significantly, the device can recognize specific kinds of polarized light and accordingly send the signal in one direction or another.

Supertough, Strong Nanofibers Developed
University of Nebraska-Lincoln materials engineers have developed a structural nanofiber that is both strong and tough, a discovery that could transform everything from airplanes and bridges to body armor and bicycles. Their findings are featured on the cover of this week’s April issue of the American Chemical Society’s journal, ACS Nano. This research was funded by the National Science Foundation, the Air Force Office of Scientific Research (AFOSR) and a U.S. Army Research Office Multidisciplinary University Research Initiative grant.
