The speed limit for intra-chip communications in microprocessors of the future

Researchers at the Moscow Institute of Physics and Technology have developed a theory that gives the possibility to precisely predict the level of noise caused by the amplification of photonic and plasmonic signals in nanoscale optoelectronic circuits. In their research published in Physical Review Applied, the scientists propose an approach that can be used to evaluate the ultimate data transfer rates in the emerging optoelectronic microprocessors and discover fundamental limitations on the bandwidth of nanophotonic interfaces.
