A 2×40 Gbps wireless communication system using 0.14 THz band oritho-mode transducer

Based on 16QAM modulation, a 2×40 Gbps wireless communication demonstration system using 0.14 THz band oritho-mode transducer (OMT) is presented in this paper. The OMT is used for polarization division multiplex (PDM) transmission of the 0.14 THz band wireless link. The measured cross polarization discrimination (XPD) of the designed OMT is more than 30 dB at 0.14 THz band, while the insertion loss is less than 1 dB. With this OMT, the wireless link succeeds in data transmission of 2×40 Gbps data over 1.5m with bit error rate (BER) <; 10^-6, SNR > 23 dB.
