“…It is noticeable that the spectrum of a 5th-order derivative Gaussian pulse is effectively compliant with the FCC indoor mask. We have recently proposed and demonstrated a simple, cost effective method based on relaxation oscillations of a semiconductor laser to generate UWB pulses with complex shape [27], [28] and the method will be presented in Section III.…”

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.

Abstract-We present and compare experimental results for electrical and photonic generation of 2-Gb/s pulses for impulse radio ultra-wideband on fiber transmission systems based on direct current modulation of a semiconductor laser diode and external optical injection of a semiconductor laser diode, respectively. We assess the performance of the two generation approaches in terms of bit-error rate after propagation over 20 km of optical fiber followed by wireless transmission.Index Terms-Impulse radio ultra-wideband (IR-UWB), personal area networks, radio-over-fiber, short range wireless link.

“…As a result, achievable wireless transmission distance is limited in a few meters. To extend the reach of UWB services, UWB-over-fiber technologies with different schemes have been proposed recently [4][5][6][7][8]. Additionally, some works have demonstrated the possibility to increase the spectrum efficiency of WDM-PON networks and optical in-home networks by simultaneously transmitting baseband and the electrically generated UWB signals [9,10].…”

“…At the CO, for a channel, a high-speed baseband signal drived a directly modulated laser (DML) to generate a UWB signal based on relaxation oscillations [5]. The lightwave from the laser was launched into a March-Zender modulator (MZM) which was driven by the second baseband signal.…”

Abstract-We propose a compact integration system to simultaneously provide wireline and wireless (baseband and ultra-wide band (UWB)) services to end-users in a WDM-PON. A 1-Gbps UWB signal is optically generated and shares the same wavelength with the baseband signal. Error-free performance was achieved after 23-km single mode fiber (SMF) transmission for both signals and additional 0.4-m wireless transmission for the UWB signal. The low complexity and high spectrum efficiency of this system makes it attractive for deployment of in wireline/wireless converged gigabit optical access networks.Index Terms-Microwave photonics, passive optical network (PON), radio over fiber (RoF), ultra-wideband (UWB), wavelength division multiplexing (WDM).
