On the Phase Noise Performance of Nonlinear Double-Loop Optoelectronic Microwave Oscillators
We consider an optoelectronic oscillator for ultrapure microwave generation with two nonlinearly coupled delay loops in which the output of one of the loops modulates the other. We introduce a suitable dynamical model and study the phase noise performance. Tuning the parameters of the second loop al...

| Sumario: | We consider an optoelectronic oscillator for ultrapure microwave generation with two nonlinearly coupled delay loops in which the output of one of the loops modulates the other. We introduce a suitable dynamical model and study the phase noise performance. Tuning the parameters of the second loop allows to reduce the detrimental effect of the multiplicative phase noise and damp delay-induced spurious peaks. Besides, the nonlinear dynamics allows for stable microwave emission with larger amplitude than a single loop system. |
