Abstract
Devices and techniques for achieving signal filtering in RF or microwave frequencies by optical filtering via two optical resonators in two separate optical paths. One optical resonator is tunable to tune the filtering in RF or microwave frequencies. Tunable opto-electronic oscillators may be constructed based on described filters.
