Side Band Suppression For Wide Band Optical Rof Systems

In this paper, we propose a flexible monocycle generator that is based on multi-tonal excitation of a dual-arm MZM. The proposed generator permits the generation of different waveforms, such as Gaussian, first order Gaussian derivative, sinusoidal, cosine and sinc pulses. We exploit the proposed generator in order to generate the International Telecommunication Union-Radiocommunication(ITU-R) recommended channelization which contains four carrier frequencies, spaced by 2.16 GHz (58.32 GHz, 60.48 GHz, 62.64 GHz and 64.80 GHz). This millimeter waves (mmwaves) have attracted a great deal of attention in the Radio over Fiber (RoF) systems. The main challenge of the RoF system is to provide higher bands and increase significantly data rate with using millimeter-wave (mm-wave) band.
