Abstract

The authors present an expanded porous polytetrafluoroethylene terahertz fibre transmission link using resonant tunnelling diodes integrated with photonic‐crystal waveguides as a transmitter and a receiver. The measured coupling efficiency between the terahertz fibre and the photonic‐crystal waveguide integrated with a silicon tapered coupler is ∼30% with a 3 dB bandwidth of 50 GHz at the 0.3 THz band. Error‐free 10 Gbit/s transmission and uncompressed 4 K high‐definition video transmission have been successfully demonstrated using 1 m‐long terahertz fibre.
