Abstract

We experimentally demonstrate photonic generation of a multichannel THz wireless signal at 200 GHz, with data rate up to 40 Gb/s QPSK modulation format using an optical heterodyne technique and digital coherent detection. The BER measurements were carried out for three subcarriers each modulated with 5 Gbaud QPSK or for two subcarriers modulated with 10 Gbaud QPSK, giving a total speed of 30 Gb/s or 40 Gb/s, respectively. The proposed system can provide a high-speed wireless transmission capability by using spectrally efficient subcarrier channels that increase the overall speed and reduce the requirement for electronic bandwidth.
