Dispersion is one of the major limiting factors for microwave/millimeter wave generation in microwave photonics. In this paper, we analyze the individual and combined effect of second order-, third order-, fourth order and fifth order dispersion parameter on microwave/millimeter wave generation. We have used the two cascaded Mach-Zehnder modulators in our proposed model, which have been not discussed earlier. Intensity at the output of photodetector versus modulation depth (β) with effects of dispersion parameters have been discussed and it has been found that output intensity of photodetector reduces when dispersion term up to fifth order are added.
