In this paper, we experimentally demonstrate a method to generate frequency-doubling photonic 16-quadrature-amplitude-modulation (16QAM) vector millimeter-wave (mm-wave) signal by using a single phase modulator (PM) with amplitude and phase precoding technique. The PM is driven by a 2-Gbaud 16QAM modulated precoded vector signal at 20GHz. We transmit the generated optical radio frequency (RF) signal at 40GHz over 22-km single-mode fiber, and after heterodyne beating in a single-ended photodiode (PD), 40-GHz electrical vector mm-wave signal displaying regular 16QAM modulation can be generated with a bit-error-ratio (BER) less than the hard-decision forward-error-correction (HD-FEC) threshold of 3.8×10 -3 . To our knowledge, this is the first time to demonstrate high-order QAM vector mm-wave signal generation based on a single PM.

“…These ROF systems are characterized by cost-effective configurations, [14][15][16][17] converged configurations, [18,19] or up to Tbit/s data rate. [20,21] Here, most importantly, it should be highlighted that low EMI is ensured in these ROF systems, due to the low RF emission power from the small fiberfed distributed coverage and the electromagnetic radiation-free optical fiber links. These characteristics of ROF are really helpful for implementing low-EMI wireless access in aircraft cabins.…”

2015):Investigation on electromagnetic environment of radio-over-fiber-based broadband wireless access scheme in aircraft cabin, Journal of Electromagnetic Waves and Applications, Broadband wireless access services inside aircraft cabin are highly desired, but they may bring severe electromagnetic interference (EMI) threats to the avionic system and the flight safety. A radio-over-fiber (ROF)-based distributed scheme is proposed to provide onboard wireless access services. Due to the low emission power of the ROF-based distributed antennas and the electromagnetic radiation-free fiber links, the proposed scheme can effectively reduce the EMI threats from the in-flight wireless access. To evaluate the electromagnetic environment of the ROF-based distributed access scheme, the coupling electric field inside the cabin is calculated by using EMPIRE-XCcel (electromagnetic simulation software). Taking the aircraftAdvanced Regional Jet for the twenty-first century (ARJ21) for example, the results show that inside the cabin, a reduction of 4-8 dB in the coupling electric field strength is achieved using the ROF-based access scheme, compared with that in conventional centralized system. Meanwhile, a higher energy efficiency is ensured as well. Likewise, lower coupling electric field strength can also be provided for other large-size aircrafts of Airbus and Boeing, by using the ROF-based distributed scheme.

“…Currently, two main trends are impacting the RoF field: migration towards higher frequency bands and increase of the channel capacity. Frequency bands below 10 GHz are already overcrowded, and therefore, open systems are looking for more spacious transmission bands such as 60 GHz [3][4][5], 75-110 GHz [6][7][8][9] and even sub-THz [10]. The W-band (75-110 GHz) is attractive because of its wide frequency bands, and seems to be an accepted good choice for transmission capacities in the order of multi-gigabits.…”

Abstract-We present a bidirectional wireless bridge in the W-band enabling the seamless convergence between the wireless and fiber-optic access networks. In the downlink, a 16 Gbit/s QPSK signal is photonically up-converted at the wireless transmitter and electrically down-converted at the wireless receiver. The down-converted signal is re-modulated on to the lightwave and transmit further through the fiber-optic system. In the uplink, both up-and down-conversion are performed by electrical means. Furthermore, we investigate both passive and active wireless transmitters in this work for both downlink and uplink transmissions. With an active wireless transmitter, up to 15 meters wireless transmission is successfully achieved with a BER below the 7% FEC limit in the downlink.
