“…As a result, it is hard to find an electrical filter which is narrow enough to obtain single mode oscillation. The dual-loop OEO with two different length delay lines has solved this tradeoff and attracted considerable attention [7,8]. The long loop of the structure is used to increase the modes suppression and reduce the phase noise of the system.…”

A novel dual-loop technique was proposed for single-mode selection in an optoelectronic oscillator (OEO). It consisted of a pump laser and a feedback circuit including an intensity modulator, a Fabry-Perot (FP) etalon, two optical fiber delay lines, two photodetectors, and an amplifier. By inserting the Fabry-Perot etalon, the proposed dual-loop OEO realized a single mode oscillation ranging from 0 Hz to 20 GHz. The strong oscillation mode was present at 15 GHz, and the side modes suppression ratio (SMSR) exceeded 140 dB. More over the length of the two fiber loops were just 5 meters and 36 meters.

“…An alternative solution instead of using delay lines in OEOs, is the use of optical resonators [2], [3]. Optical quality factors (Q opt ) as high as 10 8 to 10 11 may be obtained with different types of optical resonators: fiber ring resonators (FRRs), monocrystalline disks, silica spheres or toroids, FabryPerot ultra stable cavities… Using these optical resonators, the equivalent microwave quality factor is linked to the optical quality factor by the relation below:…”

Abstract-Optoelectronic oscillators based on high Q optical resonators are presented in this paper. These oscillators use a Pound-Drever-Hall laser stabilization technique and two different types of resonators: fiber ring and monocrystalline disk resonators. Noise processes in the oscillators are discussed, particularly the influence of the laser noise conversion and nonlinear optical scattering noise. A modeling approach using CAD software is also proposed.

“…An elegant method to reduce the oscillators' dimensions and/or to increase the Q factor is to carry the microwaves on another wave, like acoustic or optical waves [2] for example. In this study, an optical carrier at 1.55 µm is used.…”

Abstract-In order to improve the phase noise of high purity OEO based on optical resonators, like resonant fibre rings, these oscillators have been theoretically studied in terms of white frequency noise. We present here the optimization of the performances of a fibre ring resonator and the experimental phase noise results we obtained for the OEO based on an optimized very high quality factor optical resonator.
