In order to generate optical Ultra-Wideband (UWB) pulse train with a switchable shape, a novel method based on a Polarization Modulator (PolM), a Polarization Controller (PC) and a delay line, is proposed and experimentally demonstrated. Experimental results show that when a Gaussian pulse is applied to the PolM, under different phase shifts introduced by the PC, a gauss or gauss doublet pulse will be generated at the output of the Polarization Beam Splitter (PBS). If the two-path signals after PBS are properly delayed, Gaussian monocycles or third-order gauss pulses will be generated at the output of the Polarization Beam Combiner (PBC).
