“…The idea of using an optical filter, which the ODI essentially is, directly after an SOA to properly engineer the chirp imposed on the pulses passing through, has been undertaken before. However this has been done in various applications of SOA-based switches whose operation relies on the change of the SOA response incurred by one signal and suffered by another [23][24][25][26][27][28][29]. On the contrary in our case the modification of the SOA gain dynamics is provoked by a data-modulated signal onto itself, and so the approach required for removing patterning is different from a physical perspective.…”
