Abstract

We investigate the phase noise performance of an optoelectronic oscillator based on a calcium fluoride high quality factor whispering gallery mode optical resonator (WGMR). In the oscillator setup, a particular attention is given to the stabilization of the laser lightwave onto an optical resonance of the WGMR. Once the laser is stabilized, different resonant optical modes are characterized in the microwave domain. Afterwards, phase noise spectra of different oscillations at different modes of the WGMR are measured. Phase noise levels below -93 dBc/Hz and around -90 dBc/Hz at 10 kHz offset frequency from 6.35 GHz and 12.7 GHz carriers are respectively obtained.
