Researchers from Duke University in the US have developed ultra-fast light-emitting device that is able to "blink" at a speed of 90 billion times a second. The so-called plasmonic in the future can be used in optical computers to transfer data between traditional electronic microchips. This will greatly increase the speed of their work.

But first you need to create a special device, the light source is capable of "blinking". And the scientists were able to make the first step in this direction, reports PhysOrg.

When the laser emits light in a silver cube width of 75 nm, the free electrons oscillating movement, which in turn creates its own glow that reacts with electrons. This leads to an intense electromagnetic field between the silver cube and a thin plate of gold. The field interacts with the semiconductor material disposed between nanocubes and gold, and produces a directional radiation of photons, which can reach frequencies of 90 GHz.

"the Ultimate goal of our work is to implement the technology into devices that can be excited optically or electrically", scientists say.
