Abstract :
A novel and simple method to generate an ultra-wideband (UWB) doublet using an electro-optic intensity modulator (EOM) is proposed and experimentally demonstrated. The EOM is biased at a nonlinear region near the maximum or minimum point of its transfer function. When a Gaussian pulse is applied to the EOM, the pedestal or the peak part of the pulse is inverted, leading to the generation of a UWB doublet
