Abstract: In this study, we propose the design and simulation of all optical Ultra Wide Band (UWB) Dense Wavelength Division Multiplexing (DWDM) laser communication system. The proposed system was been simulated under different operation conditions. A simulated system consist of a laser sources, semiconductor optical amplifier and optical modulator. 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 30 psec. After derivative the monocycle pulse, the doublet pulses was obtained with 21 psec. All optical UWB pulses was interleaving over DWDM channels with 50 GHz channel spacing and 10 Gb/sec data rate using ON-OFF keying modulation technique.
