Abstract

I report on Nyquist wavelength division multiplexing (WDM) communication in the terahertz (THz)-band for improving the transmission capacity, whose received signal is processed with high-speed optical technology. The Nyquist WDM signal in the THz-band is generated from an optical Nyquist WDM signal by photo-mixing. The received THz-wave Nyquist WDM signal is down-converted into a radio-frequency signal, and is again transferred to an optical signal through an optical intensity modulator. Then, the desired Nyquist WDM channel in the reproduced optical signal is demultiplexed with an optical filter. I present the operating principle of the proposed procedure and its some preliminary experimental results using a 2 × 40 Gbit/s Nyquist WDM signal.
