“…Both technologies together, FTTH and wireless access networks, are also known as radio-over-fibre (RoF)-based opticalwireless networks. The most promising solution to satisfy the users growing demand on future broadband access networks, providing capacity, coverage, bandwidth and mobility, is the combination of RoF with future WDM-PON [2]. Amongst other wireless technologies, ultra-wideband (UWB) has several advantages such as low power consumption, immunity to multipath fading, interference mitigation, carrier free, high data rate and capability to penetrate through obstacles [3].…”

We propose a solution for reconfigurable wiredwireless converged networks with high data rates, based on directly modulated tunable vertical cavity surface emitting lasers (VCSEL). Wired-wireless converged networks require simple and low-cost solutions for the generation of the UWB signal in the optical domain. Direct modulation of VCSEL in combination with optical filtering enable a low-cost generation of ultra-wideband (UWB) pulses. VCSEL typically show large direct modulation bandwidths 10 GBit/s due to their short cavity related short photon lifetime. Another advantage of the short cavity is its inherent large free spectral range (FSR) which enables ultra wide continuous wavelength tuning.

“…Ultrafast optical/microwave waveforms with a bandwidth up to tens/hundreds of Gigahertz could find applications in numerous fields, such as high speed optical communications, biomedical imaging, and coherent control in chemistry [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Photonics-assisted techniques have attracted much attentions thanks to their applications in many fields [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], such as microwave frequency measurement, analog-to-digital conversion, microwave photonics sensing, broad bandwidth radar and microwave photonics filter.…”

This paper reviews recent progresses on optical arbitrary waveform generation (AWG) techniques, which could be used to break the speed and bandwidth bottlenecks of electronics technologies for waveform generation. The main enabling techniques for optically generating optical and microwave waveforms are introduced and reviewed in this paper, such as wavelength-to-time mapping techniques, space-to-time mapping techniques, temporal pulse shaping (TPS) system, optoelectronics oscillator (OEO), programmable optical filters, optical differentiator and integrator and versatile electro-optic modulation implementations. The main advantages and challenges of these optical AWG techniques are also discussed.

The integration of ultra-wideband (UWB)-over-fiber into passive optical network (PON) is of great interest as it benefits the high bandwidth capability from optical network technologies and the high flexibility from wireless network technologies. The later can only be done with a reasonable cost when a universal optical transmitter, which is capable of generation both UWB and PON signals, is available. Direct modulation of semiconductor laser was demonstrated to be suitable for high bit-rate PON systems, however the generation of UWB signals by this technique is still challenging. Using the chirp properties of directly modulated semiconductor lasers, UWB signals are generated. Different UWB signal waveforms and polarities are obtained. The received electrical spectra conform to the requirements of indoor UWB systems.
