An on-chip broadband terahertz topological beamformer using valley vortices enables efficient, reconfigurable, and high-capacity wireless communication for future 6G to XG networks.
Tiivistelmä
The content presents an innovative on-chip topological beamformer for terahertz (THz) wireless communication, which is crucial for enabling high-capacity, low-latency, and extensive connectivity in future 6G to XG networks.
Key highlights:
The beamformer leverages valley vortices for waveguiding, splitting, and isolation in a densely packed waveguide phased array, achieving complete 360° azimuthal beamforming with gains up to 20 dBi.
Using neural-network-assisted inverse design, the beamformer can radiate THz signals into free space with customizable user-defined beams.
Photoexcitation enables reconfigurable control of the THz beams, allowing for dynamic beam steering and adaptation.
The low-loss and broadband beamformer enables a 72-Gbps chip-to-chip wireless link over 300 mm and eight simultaneous 40-Gbps wireless links, demonstrating its potential for terabit-per-second 6G to XG wireless communications.
The all-silicon beamformer is CMOS-compatible, enabling large-scale integration and deployment for massive SIMO and MIMO systems.
