摘要

A novel scheme for ultra-wideband(UWB) monocycle pulse generation is proposed based on a dual-output push-pull Mach-Zehnder modulator(MZM).The MZM is driven by a non-return-to-zero(NRZ) data sequence and biased at the nonlinear point to generate edge-triggered pulses.To combine the complementary pulses forming a monocycle UWB pulse,two schemes are used to implement incoherent summation structure. A proof-of-concept experiment of UWB-over-fiber down-link system is set up.Further,by using digital signal pr...
