On a Single Loop Optoelectronic Oscillator Using Variable Centre Frequency Dynamic Filter

The present paper considers the influence of a variable center frequency tuned circuit replacing the narrowband RF filter in a conventional optoelectronic oscillator. The free-running amplitude and normalized frequency of such a system are derived and theoretical analysis coupled with experimental results showing good agreement are presented. Finally, the frequency control arrangement for such a system in response to an angle modulated signal is reported.
