| Résumé | We report an investigation on optoelectronic oscillators based on a combination of a fiber delay line and a whispering gallery mode resonator. We analyze the dynamical processes which are key for the understanding of the spectral purity of these oscillators. We therefore show how combining both optical elements leads to significant improvement of the spectral purity of the oscillator, as it leads to a spurious rejection rate higher than 50 dB. |
