Abstract

In this work we present a computer simulation of a simple technique for the generation of power-efficient, FCC-compliant Ultra-Wideband (UWB) (monocycle and doublet) pulses. A Simulated system consist of a laser sources, semiconductor optical amplifier, optical modulator, fiber Bragg grating (FBG).This technique based on combination of optically reconfigurable photonic microwave delay-line filter and using the cross gain modulation (XGM) in Semiconductor Optical amplifier (SOA). In SOA the cross gain modulation (XGM) technique was used to produce a UWB monocycle pulse with a full width at half-maximum of 35 ps, by entering the output monocycle pulses from first stage to the second stage that included reconfigurable photonic microwave delay-line filter the last act as first- or second-order difference, which can be approximated as a first- or second-order derivative, after derivative the monocycle pulse the doublet pulses was obtained.
