Abstract

I report a seamless method to convert a high-speed single-channel signal in the terahertz (THz)-band into an optical signal by using heterodyne detection, optical intensity modulation, and optical filtering. A spectral-efficient singlechannel 40 Gbit/s signal in the THz-band, which was generated from a 40 Gbit/s optical signal shaped with a Nyquist filter, was converted into an optical signal. A sideband of the converted optical signal was extracted with another filter, and the extracted signal was transmitted to a fiber-optic link. I explain the characteristics of the optical signal passed through a single-mode fiber. The signal could be transmitted to a 9 km-long fiber without chromatic dispersion compensation.
