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.

Researchers have observed ‘Luttinger-liquid’ plasmons in metallic single-walled nanotubes. This holds great promise for novel plasmonic and nanophotonic devices over a broad frequency range, including telecom wavelengths.
