20 February 2018 Optoelectronic oscillator utilizing high-Q active ring resonator
Author Affiliations +
A novel optoelectronic oscillator utilizing high-Q active ring resonator based on semiconductor optical amplifier and optical filter is proposed and demonstrated. The ring resonator with high Q-factor can reduce the dissipation of energy in the feedback loop to achieve oscillation with low phase noise. A high-quality microwave signal with a frequency tunable from 8 to 12 GHz is generated by employing a commercial tunable electrical bandpass filter. The single-sideband phase noise of the generated 10-GHz signal is measured to be -124 dBc/Hz at 10 kHz.
