- Abstract
In work, a new method of optical microwave signal generation with frequency 18-tupling using three parallel polarization modulators (PolMs) was proposed, in which the PolM is integrated through a polarization beam splitter, two phase modulators, an electrical phase shifter, and a polarization beam coupler. To generate a frequency 18-tupling millimeter-wave (mm-wave) signal, the polarization controller must first be employed to bring out linearly polarized light. Next, the linearly polarized light is faded into three PolMs to be modulated by a radio frequency signal, which can achieve multi-frequency optical sidebands. Last, controlling a polarizer to cancel unwanted optical sidebands to obtain ±9th optical sidebands is used to generate an 18-tupling mmwave signal. We have conducted detailed mathematical formula derivation and computer simulation for the scheme. The results show that the scheme can be experimentally realized and accurate enough with the performance of the signal: the optical sideband suppression ratio can reach 48.02 dB, and the radio frequency spurious suppression ratio can reach 42.25 dB, almost equal to the theoretical model.
