Researchers at the universities of Exeter and Oxford in the U.K., along with colleagues at Germany's University of Münster, have developed a nanoscale device that is programmable with either photons or electrons.

The incompatibility of electrical and light-based computing system is based on the fundamentally different interaction volumes for electrons and protons.

The researchers solved this problem by combining concepts from integrated photonics, plasmonics, and electronic memory technologies to deliver a compact device that can operate simultaneously as an optical or electrical memory and as a processor.

Exeter's C. David Wright said, “Electronic and photonic computing each have their own advantages and disadvantages: it may be, by exploiting devices such as those we have developed in this work, that we can, ultimately, achieve the best of both worlds by working seamlessly in both domains."
