Tianjin University Light Vortex Research for Reliable Wireless Data Transmission
The researchers from Tianjin University developed a reliable light vortex which can be used for wireless data transmission. The scientists at Tianjin University built an optical system which can produce and control stable light vortex patterns. The doughnut shaped skyrmions do not break apart when faced with outside disturbances. The structures maintain their stability which enables their usage as information carriers in advanced wireless communication technologies.
The system operates within the terahertz frequency range. The system permits users to change between electric and magnetic light vortex modes whenever they require. The system needs this capability because it must encode and transmit and retrieve data in environments where signal distortion occurs.
The breakthrough relies on a nonlinear metasurface. This material consists of an extremely thin structure which contains nanostructures that allow light to be manipulated in ways that traditional optics cannot achieve. The researchers use laser pulse polarization changes to create various terahertz radiation vortex states. The method enables reliable signal modulation through its compact design which eliminates the need for standard equipment.
The research team concentrates on creating a compact version of the system today. The technology will achieve better data encoding density when its physical dimensions become smaller. The development of smaller and more effective systems will advance terahertz light control technology into real world applications for high speed wireless networks.
