Scientists at the University of Adelaide have developed a new polarisation multiplexer that promises to release the potential of 6G communications. 6G is expected to be faster than 5G, with speeds up to one terabyte per second compared to 5G's peak speed of 20 gigabits per second. By operating at terahertz frequencies, these systems can support unparalleled bandwidth, enabling ultra-fast wireless communication and data transfer. A significant challenge in terahertz communications is effectively managing and utilising the available spectrum. Now, the team has developed the first ultra-wideband integrated terahertz polarisation (de)multiplexer implemented on a substrateless silicon base that they tested in the sub-terahertz J-band (220-330GHz) for 6G communications and beyond.

Future #wireless #networks are expected to make better use of limited radio frequencies with the help of smart transceivers. The authors propose a promising transceiver design using #stacked #intelligent #metasurfaces (#SIMs). An SIM is made by layering an array of programmable metasurface layers. Each layer contains many inexpensive passive elements that can individually control electromagnetic waves. By properly configuring the passive elements, an SIM can perform advanced signal processing tasks like #MIMO #precoding/#combining, #interference #mitigation between users, and #radar #sensing as waves pass through the multiple metasurface layers. This effectively reduces both energy used for radio signals and processing delays. They provide an overview of how SIMs could be used in MIMO transceiver designs, including the hardware setup and potential benefits over current solutions. The authors also discuss promising application areas and identify open challenges in developing more advanced SIM designs for future wireless networks. ---- Jiancheng An, Chau Yuen, Chao Xu, Hongbin Li, Derrick Wing Kwan Ng, Marco Di Renzo, Merouane Debbah, Lajos Hanzo More details can be found at this link: https://lnkd.in/g79axK77

""" "While maintaining highly efficient electro-optical performance, we also generated soliton microcomb on this platform," says Chengli Wang, the study's first author. "These SOLITON microCOMBS feature a large number of coherent frequencies and, when combined with ELECTRO-OPTIC modulation capabilities, are particularly suitable for applications such as PARALLEL coherent LiDAR and PHOTONIC COMPUTING." The lithium tantalate PIC's reduced birefringence (the dependence of refractive index on light polarization and propagation direction) allows dense circuit configurations and ensures broad operational capabilities across all telecommunication bands. The work paves the way for scalable, cost-effective manufacturing of advanced electro-optical PICs """ _______ This is the plan...
