Optical ultra-wideband pulse generation based on incoherent optical arbitrary waveform generation

We propose and experimentally demonstrate a simple method to generate ultra-wideband (UWB) pulses with different pulse shape, based on incoherent optical arbitrary waveform generation. Pulses with opposite polarity are obtained using the phase-modulator-based dual-input intensity modulator. Monocycle, doublet and high-order UWB pulses meeting the FCC regulation are generated. Both temporal waveform and power spectral of the signal generated are evaluated.
