CPU Optical Switching Technology

IBM was able to reach a new processor type optical switch based on technology that could lead to faster data transfer rates in the near future. , the replacement of copper Directional nanowires with photons, the latest optoelecronics achievement opens the gateway to a new era in computing.
The new optical switch was still in its infancy and has its limits, but this is the first working approach to the replacement of the electron beams with pure light. Currently, semiconductor technology is still using microscopic copper wires for the transmission of electrical signals carried by the electrons. Unlike the particles of light, commonly known as photons, electrons are some drawbacks, such as slow and generate residual heat.
CPU switches used for the direct exchange of data between the processor cores in. The researchers' assessment argues that the optoelectronic may switch attention to the data transfer speed of about terabit per second, while handling several rays of light. Dramatically this improvement over the current speed of data transmission using copper interconnects, or even carbon nanowires. New technology would eliminate delays between cores and allow producers to comply with the year 2000 such switches per square millimeter silicon.
IBM recently achievement based on technology that is currently being used in fiber-optic transmission, but it was scaled to fit into the micro-chip in the universe. According to the company, chips built with optical technology rather than "old-fashioned" copper wires leading to increased productivity of computers at a much lower cost energy efficiency dramatically improved since. He claimed that optical technology will allow 100 times faster than the speed of data transfer between the processor cores in the just-tenth part of the current government.
IBM is not the only party in optoelectronics race. Other companies, including Intel, which are trying to reach viable solutions based on light to replace conventional wiring components inside chips. However, the study of technology is time-consuming and very expensive, so we should stick to the copper in the near future.
