Abstract
In this letter, we present a high-order impulse-radio ultra-wideband (UWB) pulses generator based on the processing of incoherent optical signals by a dispersive element. The full waveform reconfigurability is achieved by the control of the optical signal power spectral density profile. Operation principle is experimentally shown by the generation of classical UWB pulses: monocycle and doublet. High-order UWB pulses generation is experimentally demonstrated by the generation of triplet and quadruplet. Also, the proper adjustment of the optical signal power distribution permits to reduce the baseband content of the synthesized waveform, which is critical in UWB environments to achieve spectrally efficient solutions. Moreover, system flexibility allows the adaptation to a bi-phase modulation scheme. This feature has been proved by the generation of the inverted version of the UWB pulses achieved in this letter.
