Researchers develop an optical technology having secure and high-capacity data transmission through innovative vortex beams, upgrading the communication systems globally.
A team of researchers from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Sciences (CAS), China has developed an optical technology to transform data transmission. The innovation employs spatial-frequency patching metasurfaces, making light beams to transmit vast amounts of information through multiple independent channels, addressing the limitations of traditional optical systems.
This newly developed method generates “super-capacity perfect vector vortex beams” (SC-PVVBs), characterised by their ability to carry extensive data volumes with much better security. Unlike conventional optical beams, which rely on global phase modulation, SC-PVVBs utilise localised spatial-frequency control to create distinct, independent data channels. This advancement leads to efficient data communication, secure encryption, and novel optical applications.
According to the research team, “The proposed vortex beam can carry vast amounts of information, making it ideal for dense data communication systems.” These beams are particularly beneficial for industries requiring high-security data management, such as telecommunications, defense, and finance. Organisations working in optical encryption or advanced communication networks can also use the technology to improve their systems.
A crucial aspect of this innovation is its multidimensional control over light beams. By manipulating spatial intensity and polarisation locally, researchers demonstrated the creation of at least 13 separate data channels. These channels, embedded across three-dimensional structures of the beam, maximise information capacity and security. This was achieved using a specially designed Dammann grating, highlighting the technology’s versatility.
Beyond telecommunications, the technology holds promise for diverse applications such as optical encryption, advanced secure communication systems, and particle manipulation. The sturdy control over the beam’s morphology and polarisation angles keep ultra-secure data systems suitable for futuristic communication needs.
By combining increased capacity and heightened security, SC-PVVB technology represents a monumental leap in optical information science, opening doors to transformative advancements across various sectors. Researchers believe this breakthrough could redefine the future of data transmission and encryption technologies globally.
