Abstract

The invention belongs to the technical field of microwave photonics, and particularly relates to an anti-interference microwave photon generation system method, in particular to a diversity signal generation method based on a double-domain mode locking technology. Comprising the following steps: step s1, driving an optical carrier by a driving signal, entering an OEO system through a phase modulator to form a closed OEO loop, and outputting the other branch to an oscilloscope and a spectrum analyzer for observation and analysis; and S2, inputting a low-frequency signal of which the frequency is integral multiple of the free spectral range of the loop oscillation mode at a radio frequency input port of the intensity modulator, introducing periodic intensity modulation into the cavity, realizing modal locking of each oscillation frequency and obtaining stable multimode oscillation. And s3, a driving signal is input into the laser, the period of the driving signal is kept consistent with the free spectral range of the loop oscillation mode, and a frequency comb signal generation system with different center frequencies and bandwidths can be generated by utilizing the double-domain mode locking principle of active mode locking and Fourier domain mode locking.

Description

technical field [0001] The invention relates to the technical field of microwave photonics, in particular to a diversity signal generation system and method based on dual-domain mode locking technology. Background technique [0002] Optoelectronic oscillators (OEO) are widely used in radar, sensing, signal processing and communication systems due to their advantages of producing high frequency, low phase noise, high spectral purity, and high stability microwave signals. However, although the device can generate microwave signals with adjustable frequency and low phase noise, the generated waveform is continuous in the time domain. In addition to continuous single-frequency signals, pulsed microwave signals with fixed carriers also play an important role in modern scientific systems. For example, high-power pulsed microwaves should be used for long-range detection in early warning radars; Temporal wide bandwidth microwave pulses. Therefore, the direct generation of pulsed m...
