Abstract
Terahertz communication meets the increasing bandwidth requirements since its advantages of large capacity and high transmission rate. In this paper, an experimental scheme for transmitting 128QAM-OFDM terahertz signal on the optical fiber downlink is proposed. In this scheme, 10Gbit/s 128QAM-OFDM optical access signals are transmitted over 20 km single-mode fiber (SMF), and the coherent reception of 0.1 THz 128QAM-OFDM electrical signals is achieved by using the self-mixing technique. The results show that the downstream 128QAM-OFDM signal not only has higher spectral efficiency but also the value of the receiver sensitivity is lower than −10dBm when the bit error rate (BER) is 10−3.
