Abstract
In this paper, the optoelectronic oscillator module with double-loop configuration and all-optical gain is presented. The oscillator module simultaneously provides ultra-low phase noise of –142 dBc/Hz at 10 kHz offset from 10 GHz oscillation frequency and low spurs level of –91 dBc. Additionally, the closein phase noise behavior at low offset frequencies is studied with respect to the influence of flicker noise.
