The key components of this system is an integrated Mach-Zehnder interferometer with two SOAs and an optical processing unit. The fusion of these two components permits the generation and customization of UWB monocycle pulses. The polarity of the output pulses is easily modified through the single selection of a specific input port. Moreover, the capacity of transmitting several data sequences is demonstrated and the potentiality to adapt the system to different modulation formats is analyzed.This work was supported in part by the National Project under Grants TEC2010-21303-C04-02 and TEC2011-26642, through the Ministerio de Economia y Competitividad; in part by the FEDER under Projects UPVOV08-3E-008 and UPVOV10-3E-492; in part by the Generalitat Valenciana through the Research Excellency Award Program GVA PROMETEO under Grant 2013/012, Next Generation Microwave Photonic technologies.Moreno, V.; Rius Mercado, M.; Mora Almerich, J.; Muriel, MA.; Capmany Francoy, J.
