Microwave Photoelectric Oscillator is a high-frequency microwave signal generator based on microwave photon technology. It can generate microwave signals with super high spectral purity and ultra-low phase noise. The phase noise generation mechanism and phase noise spectral density of typical microwave optoelectronic oscillators are studied. Based on the core devices that constitute the microwave optoelectronic oscillator, the sources of additive noise and their effects on the phase noise are analyzed in the open-loop state.
