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.

Throughout decades of research on solar cells, one formula has been considered an absolute limit to the efficiency of
such devices in converting sunlight into electricity: Called the Shockley-Queisser efficiency limit, it posits that the
ultimate conversion efficiency can never exceed 34 percent for a single optimized semiconductor junction. Now, researchers
at MIT have shown that there is a way to
This new technology can accurately detect where the user's finger is and what it is touching, and uses off-the-shelf cameras
and projectors. This eliminates the need for expensive equipment and overcomes imprecise tracking—issues posed by conventional
technologies.
