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...
We investigate the physics of bidirectional injection-locking in optoelectronic oscillators (OEO). In particular, we identify the effects of injection strength on phase noise and spurious modes for a dual injection-locked OEO. Our experimental data is then used to design a numerical model of a dual injection-locked OEO. This model will be used in the future to optimize the multi-dimensional injection-locking...
Dual-loop optoelectronic oscillators are used to obtain high-frequency harmonic signal with a very low phase noise while maintaining very low spurs. However, the fundamental limits of these devices are not known. Therefore, it is essential to develop theoretical models to improve the performance of dual-loop optoelectronic oscillators (OEOs) and in particular the performance of the dual-injection-locked...
We present an experimental study of the phase noise spectrum's dependence on the loop length in OEOs. As the loop length increases, the spectrum deviates significantly from the ideal dependence.
An injection-locked optoelectronic oscillator (OEO) is investigated for the effects of simultaneous forward and reverse injections between the master and slave OEOs to find the optimized condition for low phase noise and spurious levels.
We spectrally broaden a low phase noise Yb-femtosecond similariton fiber oscillator to more than an octave bandwidth. Using the f-2f self-referencing scheme we detect and stabilize its carrier envelope offset frequency.
