While the optical fiber is still being deployed in France, Japanese researchers at the University of Osaka and manufacturer of electronic components Rohm managed to create a chip that can transfer data (in the information technology (IT), data is a basic description, often coded, for one thing, a business transaction, event, etc..) wireless speeds comparable ... to those obtained by the fiber (a fiber is a basic training, plant or animal, filamentous appearance, is generally in the form of beams.) optics (optics is the branch of physics that deals with light and relations with the vision.).
Indeed, two of these chips exchanged wireless data at a rate of 1.5 Gb / s (world record) using wave (A wave is the propagation of a disturbance occurring in its wake a reversible change local physical properties. It carries energy without transporting matter.) "terahertz", located between the light waves (light refers to electromagnetic waves visible to the human eye, that is to say, included in wavelengths from 0.38 to 0.78 micron (380 nm to 780 nm on ...) and radio waves on the electromagnetic spectrum (the electromagnetic spectrum is the decomposition of electromagnetic radiation according to its different components in terms of frequency energy photons or ...). These chips were developed by using the tunnel (a tunnel is an underground passage to delivering a channel of communication (railway, canal, road, footpath) . ...), are discovered by a researcher (Researcher (female researcher) means a person whose job is to do research. It is difficult to clearly define the profession of researcher ...) Japanese (Leo Esaki ) who received the Nobel Prize in Physics (The Nobel Prize in Physics is a prize awarded by the Nobel Foundation in the field of physics.) in 1973 for this development. Researchers say that it is possible with this technology (The word has two meanings of technology made:) to reach a speed (the speed is a physical quantity which measures the evolution of a quantity over time.) of 30 Gb / s.
The semiconductor, with a length of two inches and a height (height has several meanings depending on the area covered.) Of a centimeter (a centimeter (symbol cm) is 10-2 m = 0.01.) is attached to an antenna (in radio, an antenna is a device to shine (transmitter) or catch (receiver) electromagnetic waves.) size of a grain (in Meteorology: A grain is a strong wind and of short duration which rises suddenly and is usually accompanied by precipitation. It usually occurs in the passage of a line ...) of rice. It can be produced for only a few hundred yen (a few euros). This differs significantly from the current 20 cm chip, costing millions of yen (several tens of thousands of euros) and reaching a maximum at 100 Mb / s transmission rate.
The process of mass production of these chips will be developed in order to equip future mobile phones and other electronic equipment in three or four years.
