“…Digital signal processing technology is well developed for high speed optical communications, due to its excellent capabilities to compensate channel impairments. Recent research has shown that an analog fiber link can also benefit from DSP technology, in terms of link linearity and dynamic range [55]. The signal at the receiver side is first sampled at 40 GSa/s by an Agilent Infinium DSO80000B with 13 GHz analog bandwidth and then processed offline.…”

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.

“…Furthermore, from the result, we calculated that this technique can easily achieve an optical link budget of more than 10 dB. Here, looking at recent rapid development of high-speed digital signal processor (DSP) [24], we can expect to achieve a multi Gb/s data rate by employing the high-speed DSP-based demodulator, which is capable of multi-level demodulation (QAM, OFDM, . .…”

Radio On Fiber (ROF) is an optical analog technique for transmitting RF signals. With ROF systems, the base station configuration is simple and independent of the modulation format and protocol. This advantage means that ROF is expected to become a useful way of realizing flexible and high capacity access networks. This paper reviews recent technical trends in ROF access systems, focusing especially on the millimeter-wave band. In addition, this paper describes our proposal based on an optical heterodyne technique for a 60 GHz band ROF access system, which realizes a sufficient optical link budget with a simple system configuration.
