The new chip leverages photonic topological insulators to operate in the terahertz band—not in the 5G range, but in the 6G range.
Without 5G even fully realized, researchers are already making the push toward 6G. New generations of mobile communication may require Tbps speeds, which far exceed the theoretical capacity of 5G at 10 Gbps.
As it stands right now, researchers feel that the key to 6G is finding ways to operate in the previously unoccupied terahertz band. Now, researchers at Nanyang Technological University in Singapore and Osaka University have developed a wireless chip to operate in this band.
What is the Terahertz Band?
As Dr. Neda Khiabani explains in his AAC article, terahertz (THz) radiation is generally defined as the region of the electromagnetic spectrum in the range of 100 GHz (3 mm) to 10 THz (30 μm). Compared to its neighboring microwave and optical bands, this portion of the EM spectrum is considerably understudied.
