Faster than conventional computers. That's how optical computers work.

Faster than conventional computers. That's how optical computers work. 

Processors in computers work by logic sentences, which run a binary process, namely 1 and 0. This logical process, in traditional computer processors electronically, is carried out by electrical circuits.

But researchers have discovered a way to operate these logic sentences based on light, which is a million times faster than the traditional electronic method.

This was revealed by a study conducted at AALTO University in Finland and published in Science Advances.

Computing needs for the next generation

In order to meet next-generation data processing needs, such as assessing the AI dataset, and identifying algorithmic inference sources, computing logic sentences must work faster.

The need for this development to speed up processing times stems from an increase in the enormous data sets of the Internet of Things. The ever-increasing amounts of data from sensor sources and algorithms associated with collecting and evaluating, and then making inferences from the data, need computational speeds several times higher than current ones.

New visual logic operating mechanisms

The new optical logic mechanisms, which were designed and developed by a team of Alto University scientists, are operated at a rate about a million times faster than the previous logical gates.

This extremely fast processing uses circular polarized light instead of electrical signal, largely dependent on the use of circular polarized beam, through a crystalline material sensitive to light beam.

The direction of the light beam curvature is determined by the shape of the crystal it passes. It bows either side or side, either right or left, which is the equivalent of an electric signal 0 or 1 in conventional computers but much more quickly.
