“…To combat this limitation, several solutions have been proposed to refine and improve the performance of OEOs, including the incorporation of a highly selective whispering gallery optical filter in the optical segment of the oscillator [12] that can lead to extremely compact [13], broadly tunable [14] and low phase noise [15] devices with the possibility of exploiting as well opto-mechanical effects [16]. Coupled optoelectronic oscillators (COEOs), which simultaneously produce spectrally pure microwave signals as in a OEO and short optical pulses as in a mode locked laser, have also been proposed and actively researched during the last years [17][18][19][20]. Finally, multi-cavity or multiloop OEOs have been proposed [21], where a long cavity provides the required spectral purity and a short fiber cavity provides the required spectral separation between adjacent oscillating modes, what alleviates the narrowband requirement for the internal RF filter.…”

Abstract:We propose the use of both homogeneous and heterogeneous multicore fibers to implement multi-cavity optoelectronic oscillators. We present design equations and examples that show the potential for unique performance in terms of spectral selectivity, tunability and high-frequency operation.

“…However the OEO can be used as a cheaper and more frequency flexible solution providing similar phase noise performance. One example of an optical pulse train generated by an OEO is the coupled OEO (C-OEO) presented by Yao et al [47]. As seen in Figure 8, in this configuration, the intensity modulator in the OEO is also the same as the one used in an actively-modelocked fiber laser configuration.…”

The Optoelectronic Oscillator (OEO) was first demonstrated in 1996 as a low phase noise RF source. Low phase noise RF sources have uses for multiple applications, ranging from analog to digital converters to radar to metrology. In the past sixteen years, the OEO has been shown to be useful for other signal processing applications. This paper will provide a background of the OEO's principles of operation, as well as multiple examples of signal processing applications where the OEO can be used. The OEO can be applied to both analog and digital problems, providing new techniques to solve these challenges.

“…In many applications, existence of such huge number of spurs near the main oscillation mode is unacceptable. Many techniques have been proposed for reducing the amplitude of the unwanted cavity modes such as using multiple loops in an OEO [9]- [19], dual injection-locked OEO [20]- [23], and coupled OEO [24]- [27]. However, by using these configurations not only are the spurious modes not completely eliminated but also the phase noise degrades relative to the single-loop OEO with long-fiber because the overall Q-factor is averaged between the short and long loops [20].…”

Abstract-We propose and theoretically and experimentally demonstrate a novel tunable spurious-free single-loop optoelectronic oscillator (OEO) with low drift and low-phase noise. In the proposed transposed-frequency OEO (TF-OEO), a nonreciprocal bias unit and an optical phase modulator in a fiber Sagnac interferometer function jointly as an intrinsically drift-free intensity modulator, which improves the long-term drift. Besides, a transposed-frequency low-noise filtered amplifier is used which replaces the conventional radio frequency (
