Researchers have developed a 3D gap-plasmon antenna which can focus light into a few nanometers wide space.

Researches have developed a new method for optical communication on a chip, which will give a possibility to decrease the size of optical and optoelectronic elements and increase the computer performance several tenfold. According to their article, they have proposed the way to completely eliminate energy losses of surface plasmons in optical devices.

Although the domestic solar-energy industry grew by 34 percent in 2014, fundamental technical breakthroughs are needed if the U.S. is to meet its national goal of reducing the cost of solar electricity to 6 cents per kilowatt-hour. New research could make it easier for engineers to harness the power of light-capturing nanomaterials to boost the efficiency and reduce the costs of photovoltaic solar cells.
