Effect of higher order dispersion parameters on optical millimeter-wave generation using three parallel external optical modulators

This paper presents a, both experimental and theoretical, study of the influence of higher order fiber dispersion parameter on the optical mm-wave generation using 3-parallel Mach Zehnder Modulators. Both individual and combined effects of the dispersion parameters, i.e., second order- and third order- (3OD) are investigated. This research demonstrates that the 3OD is significantly affected by the optical mm-wave propagation through the International Telecommunication Union fiber of different lengths. The results of the simulation are in good agreement with those of the experiments. The Bit error rate, Q factor, optical sideband suppression ratio, radio frequency spurious ratio, and eye diagrams are given and discussed.
