“…To move beyond this, the THz band (300 GHz-10 THz) featuring an extremely large bandwidth available between the millimeter-wave and infrared radiation is considered as the "Next Frontier" to meet the data rate target of future UWNs. In the THz band, we have recently contributed to the development of THz wireless communication by demonstrating a series of high-speed photonic wireless transmission systems in the 0.3-0.5 THz regime with multi-channel Nyquist-quadrature phase shift keying (QPSK)/16 quadrature amplitude modulation (QAM) signals, [22]- [31]. These work is enabled by ultrafast THz transceivers, particularly the availability of ultra-broadband uni-travelling photodiodes (UTC-PDs) as efficient photo-mixing emitters and Schottky diodes as broadband electronic receivers, and the highest net data rate has reached up to 260 Gbit/s [31].…”

Abstract-To accommodate the demand of exponentially increased global wireless data traffic, the prospective data rates for wireless communication in the market place will soon reach 100 Gbit/s and beyond. In the lab environment, wireless transmission throughput has been elevated to the level of over 100 Gbit/s attributed to the development of photonic-assisted millimeter wave (MMW) and THz technologies. However, most of recent demonstrations with over 100 Gbit/s data rates are based on spatial or frequency division multiplexing techniques, resulting in increased system's complexity and energy consumption. Here, we experimentally demonstrate a single channel 0.4 THz photonic-wireless link achieving a net data rate of beyond 100 Gbit/s by using a single pair of THz emitter and receiver, without employing any spatial/frequency division multiplexing techniques. The high throughput up to 106 Gbit/s within a single THz channel is enabled by combining spectrally efficient modulation format, ultra-broadband THz transceiver and advanced digital signal processing (DSP) routine. Besides that, our demonstration from system-wide implementation viewpoint also features high transmission stability, and hence shows its great potential to not only decrease the system's complexity, but also meet the requirements of prospective data rates for bandwidth-hungry short-range wireless applications.

“…Several wireless propagation demonstrations in higher frequency bands have been reported, such as 11 Gbit/s on-off keying (OOK) data wireless transmission at 100 GHz carrier frequency [16], a 40 Gbit/s wireless link at 300 GHz based on OOK data modulation and direct detection [17], real-time 50 Gbit/s OOK 300 GHz wireless transmission at over 20 m distance [18], a wireless OOK link operating at a carrier frequency of 220 GHz with a data rate of 25 Gbit/s [19], 24 Gbit/s amplitude shift keying (ASK) data wireless transmission at 300 GHz using a uni-travelling carrier photodiode (UTC-PD) emitter and a Schottky barrier diode detector [20], 200 GHz multicarrier wireless transmission using a quadrature phaseshift keying (QPSK) baseband signal and a gain-switched laser comb source [21], 25 Gbit/s QPSK hybrid fiber-wireless transmission in the W-Band (75-110 GHz) with a remote antenna unit for in-building wireless networks [22], and 60 Gbit/s QPSK wireless transmission with real-time capable detection at 400 GHz carrier [23].

Abstract:We propose and experimentally demonstrate THz photonic wireless communication systems with 16-QAM modulation in the 375-450 GHz band. The overall throughput reaches as high as 80 Gbit/s by exploiting four THz channels with 5 Gbaud 16-QAM baseband modulation per channel. We create a coherent optical frequency comb (OFC) for photonic generation of multiple THz carriers based on photo-mixing in a uni-travelling carrier photodiode (UTC-PD). The OFC configuration also allows us to generate reconfigurable THz carriers with low phase noise. The multiple-channel THz radiation is received by using a Schottky mixer based electrical receiver after 0.5 m free-space wireless propagation. 2-channel (40 Gbit/s) and 4-channel (80 Gbit/s) THz photonic wireless links with 16-QAM modulation are reported in this paper, and the bit error rate (BER) performance for all channels in both cases is below the hard decision forward error correction (HD-FEC) threshold of 3.8e-3 with 7% overhead. In addition, we also successfully demonstrate hybrid photonic wireless transmission of 40 Gbit/s 16-QAM signal at carrier frequencies of 400 GHz and 425 GHz over 30 km standard single mode fiber (SSMF) between the optical baseband signal transmitter and the THz wireless transmitter with negligible induced power penalty.
