“…However, to further take advantage of photonic technologies, it is desirable to develop the WDM-PON compatibility of photonic UWB generation methods and directly integrate the UWB signal into the optical domain. Motivated by this need, we demonstrate the integration of photonically generated Gigabit UWB into baseband WDM-PON [50]- [52] and long reach PON [53], incorporating our proposed generation method based on relaxation oscillations [51]- [53].…”

In this paper, we comprehensively review our research work on system wide implementation of photonically generated IR-UWB signals based on relaxation oscillations of a semiconductor laser. Firstly, we present our novel approach as a flexible method for photonic generation of high speed impulse radio ultra-wideband (IR-UWB) signals at 781.25 Mbps with on-off keying (OOK) and binary phase shift keying (BPSK) modulation formats. We further advance the state-of-the-art to include multi-Gigabit IR-UWB signal generation. Both OOK and BPSK signals comply with the Federal Communications Commission (FCC) regulation. Secondly, we implement UWB fiber transmission systems and study hybrid fiber-wireless transmission performance at a system level. This is accomplished by employing our digital signal processing (DSP) assisted receiver. The photonic generation method is superior to the state-of-the-art electronic generation method in terms of transmission bit-error rate performance. Moreover, photonic IR-UWB generation is shown to be capable of longer wireless reach due to its lower bandwidth limitation. Finally, we experimentally demonstrate the integration of a relaxation oscillations-based UWB photonic generation system into existing wavelength division multiplexing passive optical networks (WDM-PON) infrastructure. This provides converged Gigabit indoor wireless and wireline access services.Index Terms-Fiber-wireless access, impulse radio, relaxation oscillations, ultrawideband, UWB-over-fiber, WDM-PON.

“…Radio-over-fiber (ROF), which is a significant branch of microwave photonics, has developed rapidly to provide versatile, robust, and large-capacity wireless access services for civil and military applications. 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.…”

“…The uplink data loaded on optical carrier are then sent to the main AP via the fiber uplinks, establishing a full-duplex access system. [17] Here, a number of APs are merged together to the main AP under the wavelength division multiplexing (WDM) mode, like the operation mode in [18]. Also, the WDM mode might be employed for high-spectral-efficiency photonics-assisted frequency down-conversion in ROF system, as reported in our preliminary work in [27].…”

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.

“…In optical access networks, wavelength division multiplexing (WDM) technique is considered as a promising candidate as it can increase the total throughput as well as ensure the scalability of the network by allocating wavelengths to each end user [5,6]. However, when integrating the conventional radio-over-fiber (RoF) signals at 60 GHz and above with the dense WDM (DWDM) system with 50 GHz or 25 GHz channel spacing, the signal carriers will be filtered out by the arrayed waveguide gratings (AWG).…”
