Abstract
In order to prove that the microwave photonic frequency multiplication system can be one part of radio over fiber transmission system, the microwave photonic system based on polarization modulator with the adjustable frequency multiplication factors and without the effect of fiber dispersion was demonstrated. The system principles and characteristics of two, four and six frequency multiplication based on the polarization modulator were analyzed theoretically. The responding different schemes were designed for different frequency multiplication factors. The experimental demonstration, data analysis and experimental result discussion were carried out. The good output of frequency multiplication was achieved on the basis of the ongoing optimization of the experimental system. The results show that the frequency multiplication output of the microwave/millimeter wave signals can be up to 42GHz within the scope of the instrument allowed. The system has the advantage of the small effect of fiber dispersion.
