100 Gbps is the maximum data transmission speed achieved by researchers at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, using a newly developed silicon photonic chip. The achievement was made possible through topological photonics, which helps terahertz waves travel around designed obstacles with minimal signal loss. The researchers demonstrated this speed using a power splitter based on photonic Klein tunnelling. The technology operates in the 310–360 GHz frequency range and could contribute to developing compact, high-speed communication circuits for future 6G networks. It also offers potential for more efficient terahertz signal transmission.
