Microwave photon frequency control array signal generation device based on double optical combs and output method

The invention provides a microwave photon frequency control array signal generating device based on double optical combs and an output method. Two optical harmonic sidebands are constructed through an optical method, the two optical sidebands use two optical combs with fixed repetition frequency difference, and by utilizing the progressive increase effect of comb tooth frequency difference and adjusting the repetition frequency difference of the two optical combs and the number of comb lines, a multi-channel frequency control array signal with controllable channel number and controllable frequency offset is generated. The device is realized through an all-optical method, so as to have the characteristics of large bandwidth, frequency tuning, good channel electromagnetic compatibility, signal transparency and the like. The advantages of large bandwidth, low frequency dependent loss, electromagnetic interference resistance and the like of the microwave photon technology are utilized, and the bottlenecks of limi
