Abstract-20 Mbps wireless communication demonstration using terahertz quantum devices
Li Gu, Zhiyong Tan, Qingzhao Wu, Chang Wang, Juncheng Cao,
A wireless terahertz (THz) communication link is demonstrated, in which a THz quantum cascade laser and a THz quantum-well photo-detector (QWP) serve as the emitter and receiver, respectively. With the help of the well-matched THz QWP, the optical collection efficiency has greatly been improved. A data signal transmitted over 2.2 m with a low bit error rate (<=1 \times 10-8) and data rate as high as 20 Mbps is achieved, which are almost 1 order of magnitude higher than that previously reported.
