Optoelectronic oscillators (OEOs) are promising low phase noise radio frequency sources. However, the long fiber loops required for a high Oscillator Q also lead to spurious modes (spurs) spaced too narrowly to be filtered by standard electronic devices. As a solution to this problem, the dual injection-locked OEo (DIL-OEO) has been proposed and studied. Previously, we presented experimental data...
Optoelectronic oscillators (OEOs) are used to generate RF signals in the X-band region with a very low phase noise. These hybrid opto-electronic devices are based on a long optical fiber that forms a very high-Q RF cavity. We have studied theoretically and experimentally single-loop and dual-loop optoelectronic oscillators. Excellent agreement between theory and experiments was obtained. The results...
We derive the equations that govern the phase noise at steady state in two coupled oscillators with delay. This simple model is then applied to the dual-injection-locked opto-electronic oscillator (DIL-OEO). This model is an extension of the Yao-Maleki model from one OEO loop to two, and it is complementary to other work on full simulations and experiments that we have carried out. We use this model...
