Ultra-wideband pulses generation by means of incoherent optical processing compatible with radio-over-fibre systems

A technique for UWB pulses generation based on incoherent optical signal processing through a dispersive element is proposed and experimentally demonstrated. The generated waveform is given by the optical signal power distribution. Therefore, waveform reconfigurability is achieved by the proper control of the incoherent optical signal power distribution. UWB pulses generation have been experimentally demonstrated by means of the synthesis of monocycle and doublet waveforms using an optical channel selector to control the optical signal power distribution. Moreover, for wireless communications, the complete control on the waveform permits to fulfil the FCC spectral requirements and thus an increasing of the UWB radio signals coverage area.
