The new device comes from Australia’s global university of technology and design RMIT. the team of researchers were led by Dr Haoran Ren from the Institution’s school of science and also, Dr Zengji Yue, who is Assistant Reseach fellow at the University of Wollongong and it is possible that it might change optical communication forever. According to Ren, optical communications are heading towards a ‘capacity crunch’ as they are not able to keep up with the ever-growing demands of Big Data. the team has managed to accurately transmit data through the light at its highest capacity in a way which will allow them to increase the bandwidth.
The conventional broadband fibre optics carry information on the pulse of light via optical fibres which means that the speed of the process is affected by the way the light is encoded at one end and the processor at the other end. But this device by RMIT is capable of reading twisted light with the help of oscillation of light waves to encode the data.
This also means that it can access so much more of light’s data- carrying capacity other than just the colour of the spectrum allowed by the current broadband technologies. It does this by carrying the data on light waves which have been twisted in a spiral, which is a state referred to as Orbital Angular Momentum (OAM). Also, the materials of this device are compatible with today’s famous silicon-based options which means that there is the possibility for industry applications scaling is very accessible. The high performance and low cost of the device make it appropriate for application in the next generation’s broadband application.
