We demonstrate a terahertz fiber link using resonant tunneling diodes at 0.3-THz band. A silicon photonic-crystal waveguide is employed as the interface between the fiber and resonant tunneling diodes, for efficient coupling. We achieved error-free (bit error rate <10^-11) transmission of 10-Gbit/s data rate, as well as uncompressed 4K high-definition video transmission using the developed system.
