High-performance millimeter-wave synergetic optoelectronic oscillator with regenerative frequency-dividing oscillation technique.
OPTICS EXPRESS(2019)
Abstract
A novel millimeter-wave synergetic optoelectronic oscillator based on regenerative frequency-dividing oscillation and phase-locking techniques is proposed and experimentally demonstrated. The regenerative frequency-dividing oscillator is embedded for millimeter-wave frequency division, and then synergistically oscillates with the optoelectronic oscillator (OEO) due to injection-locking effect. The phase-locking stabilization technique is skillfully utilized in millimeter-wave OEO via commercial analog phase shifter. As a result, a 40-GHz signal is generated featuring low phase noise, high stability and low spurs. The single-sideband phase noise is about -117 dBc/Hz at 10-kHz offset frequency and the spurious suppression ratio reaches more than 80 dBc. The measured overlapping Allan deviation of the proposed synergetic OEO reaches lower than 10(-13) at 1024-s averaging time, which is five orders of magnitude lower than free-running millimeter-wave OEO.
