[Abstract]:In order to prove that the microwave photonic frequency doubling system can form part of the optical wireless communication system, a microwave photonic system with adjustable frequency doubling coefficient based on polarization modulator, which is not affected by the dispersion of the optical fiber, is adopted. The system principle and characteristics of second harmonic, fourth harmonic and sixth harmonic frequency based on polarization modulator are theoretically demonstrated and analyzed. According to the different frequency doubling coefficients, the corresponding experimental scheme is constructed, and the experimental results are verified, the data are analyzed and the experimental results are discussed. Good frequency doubling output results are achieved on the basis of the continuous optimization of the experimental system. The results show that the microwave / millimeter wave signal can reach 42 GHz in the range of the instrument measurement, and the system has the advantage of little influence by fiber dispersion.
