UWB monocycle pulse generation based on optical cross-polarization modulation

A novel all-optical method for ultra-wideband (UWB) monocycle pulses generation based on cross polar-ization modulation (CPM) effect in highly nonlinear photonic crystal fiber is proposed and demonstrated.Due to the CPM effect between the probe light and the pump pulse, a pair of polarity-reversed Gaussian pulses is produced.After proper differential delay, an UWB monocycle pulse with 84-ps width and the fractional bandwidth of 153% is generated after photodetection.
