New Silicon Chip Doubles Data Capacity for 6G Communications

Engineers develop the first ultra-wideband terahertz polarisation multiplexer, unlocking the potential for next-generation wireless technology.

The chip operates in the sub-terahertz J-band (220-330 GHz), enabling unprecedented bandwidth.
Developed by researchers from the University of Adelaide and Osaka University, it uses standard silicon fabrication methods.
The polarisation multiplexer allows simultaneous transmission of multiple data streams over the same frequency band.
This innovation promises advancements in high-definition video streaming, augmented reality, and mobile networks.
The technology is expected to see commercial prototypes and early-stage products within three to five years.
