It is shown that the phase noise spectrumdensity shift periodicity with the length of external cavity and the peak value of power spectrum density varies considerably with the feedback coupling rate.
The power densityspectrum of an inner-phase-modulated optical fiber resonator is analyzed theoretically and experimentally, which is valid for any source coherence time.
