Ultra-Fast Magnetic Switching Has Potential To Boost Fibre Optics-Cable Market
Posted On January 13, 2021
Digital Technology switches between 0 and 1, making it the spinal cord on which the whole internet works. The majority of data downloaded by humans all over the world is stored in data centers. These centers are linked to each other by a network of optical fibers.
Increasing the efficiency of this global network is of utmost importance. However, there are three main hurdles that the researchers have been combating to progress the internet further. The first problem is the speed and energy consumption of the semiconducting or magnetic switches that process and store data. The second is the fiber optic network's ability to handle it.
Recently, a group of researchers has developed a new ultra-fast toggle switching by using laser light on mirror-like films, which can turn out to be a big advancement in Fiber Optics-Cable Market. It is because films are made up of alloys of manganese, ruthenium, and gallium known as MRG and could help solve all three problems mentioned above.
It is due to the fact that light is advantageous when it comes to speed. Moreover, magnetic switches do not need any power to maintain their state. Besides, they present the possibility of rapid time-domain multiplexing of the already working fiber network-This may result in it being able to handle ten times of data.
Researchers used ultrafast laser pulses that last about a hundred femtoseconds (one ten thousand billionths of a second) to control the magnetization of thin films of MRG to and fro. The direction of magnetization has the ability to point either in or out of the film.
After every laser pulse, it brusquely flips its direction. Each pulse briefly heats the electrons in MRG by about 1,000 degrees-This leads to a flip of its magnetization.
Researchers believe that there is much left to be done to fully understand the atoms and electrons' behavior that are present in a solid. They are a long way from being called balances on a femtosecond timescale.
The team is set to follow this research by collecting data from a new pulsed-laser to do experiments on MRG and other materials. This will empower them to better understand the dynamics of the ultrafast optical response with electronic transport. They expect that these experiments with ultra-fast electronic pulses help to test the hypothesis that the origin of the toggle switching is entirely thermal.
Some team members will also contribute their expertise to another group of researchers who are working on generating even shorter laser pulses to develop this sector further.
