ptoelectronic oscillators (OEOs) with wide band radio frequency (RF) filters can be used to tune the oscillation frequency
in a wide range by using a RF phase shifter. Because of the low quality factor of the RF filter in such OEOs, some of the
non-fundamental harmonics are not negligible and should be taken into account in the steady state analysis. As in other OEOs,
generally there are a number of stable periodic solutions that each of them can be the observed solution depending on the initial
conditions. These solutions are called the oscillation modes. A frequency domain approach for computing all the oscillation
modes of wideband OEOs is presented. A stability analysis approach is presented for detecting the stability of the computed
modes. It is shown that considering an adequate number of harmonics is necessary for an accurate computation of the modes
and a valid stability analysis. The advantages of the new approach over time domain approaches to the OEO analysis are the ability
to compute all the oscillation modes, instead of only the dominant mode, as well as much less runtime and memory requirements.
The validity of the new approach is verified by comparing its results against the time-consuming time domain integrations.
