Paper Abstract

In this paper, a novel and simple all-optical scheme for generating UWB monocycle pulses based on the nonlinear polarization rotation in an SOA is proposed and experimentally demonstrated. UWB spectrum generated from 20Gb/s RZ signal has a centre frequency at about 5.0 GHz and a -10 dB bandwidth of about 10 GHz with a fractional bandwidth close to 200% which is wide enough for UWB communication. The UWB signals have been transmitted in a 100km SMF transmission link. The quality of UWB signal deteriorates with the increase in delay time between RZ and dark RZ, while the attenuation increase for RZ needs a consideration trade-off between restraint for CW and stationarity of UWB signal.
