“…For polarization multiplex (MUX) and de-multiplex (DEMUX), we used ultra-broadband wire-grid polarizers. With use of two pairs of photonics-based ASK transmitters and direct detection receivers, an error-free 300-GHz band link at 24 Gb/s for each channel has been demonstrated, which corresponds to the total throughput of 48 Gb/s [19]. Thus, the maximum data rate obtained by the SISO link can be easily doubled, for instance, from single channel 40-Gb/s data rate to the total throughput of 80 Gb/s.…”

There has been an increasing interest in the application of terahertz (THz) waves to broadband wireless communications. In particular, use of frequencies above 275 GHz is one of the big concerns among radio scientists and engineers, because these frequency bands have not yet been allocated at specific active services, and there is a possibility to employ extremely large bandwidths for ultrabroadband wireless communications. Introduction of photonics technologies for signal generation, modulation, and detection is effective not only to enhance the bandwidth and/or the data rate but also to combine fiber-optic and wireless networks. This paper reviews recent progress in THz wireless communications using telecom-based photonics technologies towards 100 Gb/s.

“…In particular, in the submillimeter-wave band at a frequency greater than 300 GHz called the "terahertz band," a possible bandwidth broader than 10 GHz helps achieve capacity greater than 10 Gb/s [3], [4], [5]. Such broad bandwidth is applicable for a simple modulation format such as on-off keying; however, the spectral efficiency will still be important in the microwave and millimeter-wave bands because of the relatively narrower bandwidth of the antenna and amplifier devices.…”

“…It should be noted that an offset parabolic antenna made from aluminum is used as the antenna for both the Tx and Rx [18]. An electrical SHM, operated at a 12.5-GHz LO signal, performs heterodyne frequency down-conversion from 325 GHz to 25 GHz. An IF amplifier optimizes the signal level for input into an ADC with a sampling speed of 160 Gs/s.…”

“…Optical-to-electrical (O/E) and electricalto-optical (E/O) conversion technologies provide direct conversion between the optical and terahertz radio signals without any processing latency, and its signal speed is much faster than 10 Gb/s [22]- [25]. IIn addition, advanced optical digital coherent detection can compensate for transmission impairments of the signal in the optical domain, even in the terahertz domain; a waveform of the signal is transported over the fiber and the air between a transmitter (Tx) and a receiver (Rx) [26].…”

SUMMARYA terahertz-wave communication system directly connected to an optical fiber network is promising for application to future mobile backhaul and fronthaul links. The possible broad bandwidth in the terahertz band is useful for high-speed signal transmission as well as radio-space encapsulation to the high-frequency carrier. In both cases, the low-latency feature becomes important to enhance the throughput in mobile communication and is realized by waveform transport technology without any digital-signal-processing-based media conversion. A highly precise optical frequency comb signal generated by optical modulation and the vector signal demodulation technology adopted from advanced optical fiber communication technologies help perform modulation and demodulation with impairment compensation at just the edges of the link. Terahertz wave, radio over fiber, waveform transport, coherent detection, multilevel modulation, radio on radio. key words: terahertz wave, radio over fiber, waveform transport, coherent detection, multi-level modulation, radio on radio
