摘要：
In this study, a microwave photon up and down-conversion signal generation scheme is proposed to realize phase tuning. The main component of this scheme is a polarization multiplexing dual-drive Mach-Zehnder modulator (PDM-DMZM). In the proposed scheme, up and down-conversion signals switching can be realized by adjusting the direct current bias point of the modulator. Further, the phase is continuously tuned by adjusting the polarization controller. The proposed scheme can be extended to a multichannel independent phase tuning system. Simulation results show that the radio frequency signal with a frequency of 10 GHz can be converted into a down-conversion signal (1 GHz) and an up-conversion signal (19 GHz). Its phase can be continuously tuned in the range of 0°360° and generated under different phases. The maximum power fluctuation of the signal is less than 0.3 dB, the spurious signal suppression ratio can be maintained above 20 dB, the maximum input frequency of the system can be adjusted from 0.5 to 65.0 GHz, and the frequency of the generated phase-shifted signal can range from several GHz to 130 GHz. © 2020, Chinese Lasers Press.
