We propose a novel approach for generating UWB signals for propagation over the optical fiber. This technique uses the effect of chromatic dispersion in single mode fibers, expressed by the Schrodinger equation. After duplicating the input pulse signal, the interference of two replica, that are unequally dispersed, results in a second order derivate of the input signal and therefore in an UWB pulse carried by an optical wave. Gaussian doublet like signals can easily be generated. This enables providing several gigahertz bandwidths for applications in high-bit-rate UWB wireless communications. New experimental schemes are given as a proof for our new approach. This new method allows not only generating UWB pulses but also distributing them over optical fibers with a low integration cost. © 2007 IEEE.
