title: Photonic generation of impulse ultrawideband signals with switchable shapes and polarities based on frequency-to-time mapping.
abstract: A photonic approach to generate impulse ultrawideband (UWB) signals with switchable shapes and polarities based on the frequency-to-time mapping technique is proposed and demonstrated. UWB monocycle, doublet, and triplet signals with two polarities can be obtained by adjusting the switchable spectrum shaper.
