AB - In this paper, we propose the design and present a simulation demonstration of a system for tunable optical generation of microwave/millimeter-wave (mm-wave) signals using digitally programmable optical frequency comb. This is the first time that digital signals have been used as an external modulation microwave source. Compared with using sinusoidal signals, the output signal of optical phase modulation driven by digital signals has flat comb lines. The average distribution of spectral energy in this way enables high-order sidebands to have higher energy, thereby reducing the energy loss of mm-wave generated by external modulation methods. By changing the center frequency of the optical narrowband bandpass filter, the frequency of the output mm-wave signal can be easily adjusted, achieving tunable optically generating mm-wave signals. The simulation results demonstrate that mm-wave generation in the Ku/Ka band of satellite communication network has been successfully realized. During the tuning process, the output mm-wave signal power stabilized at −14.5 dBm, with an optical sideband suppression ratio of 43 dB and a radio frequency sideband suppression ratio of 46 dB.© 2023 Optica Publishing Group
