The global digitalization and the recent rise of artificial intelligence-based data-driven applications have directed their vectors towards terabits per second (Tbps) communication links. The existing 5G communication architect cannot fulfill this demand due to bandwidth scarcity, which has stimulated innovative technologies with a vision of 6G communication. Terahertz (THz) technologies have been identified as a critical candidate for the emerging 6G communication with the potential to provide ubiquitous connectivity and remove the barrier between the physical, digital, and biological worlds. Nonetheless, the existing THz on-chip communication devices suffer from scattering loss, bending loss, limited data speed, and lack of active tunability. Here, I will describe a new class of active on-chip THz topological devices consisting of broadband single channel 160 Gbit/s communication link, built on Silicon Valley Photonic Crystal. Silicon topological photonics will pave the path for augmentation of CMOS-compatible terahertz technologies, vital for accelerating the development of 6G communications that would empower societies with real-time terabits per second wireless connectivity for network sensing, holographic communication, cognitive internet of everything, and massive digital cloning of the physical and the biological world.
