High-order UWB pulse generation based on a microwave photonic filter using incoherent optical sources

摘要

We propose and experimentally demonstrate a photonic pulse generator for Ultra-Wideband application which is based on a microwave photonic filter whose coefficients are obtained by slicing of a broadband optical source and the polarity is controlled by phase inversion in electro-optical modulator. High-order UWB pulses have been experimentally obtained due to the number of taps which can be easily increased. Therefore, the adaptation of the waveforms to the FCC mask is improved considerably and the efficiency of the system is increased in terms of power spectral density.
