Researchers from the Laboratory of Nanooptics and Plasmonics at the MIPT Center of Nanoscale Optoelectronics have developed a new method for optical communication on a chip, which will could decrease the size of optical and optoelectronic elements and greatly increase computer performance. According to an article published in Optics Express, they have proposed a way to completely eliminate energy loss of surface plasmons in optical devices.
"Surface plasmon polaritons have previously been proposed as information carriers for optical communication, but the problem is that the signal is rapidly attenuated propagating along plasmonic waveguides. Now, we have come very close to the complete solution of this problem. Our approach clears the way for the development of a new generation of high-performance optoelectronic chips," says Dmitry Fedyanin, the head of the research.
