“…The dual-loop and multi-loop configurations [11][12][13][14], coupled OEO [15][16][17][18], injection-locked OEO [19][20][21][22], OEO with quality multiplier [23], and OEO with feedback loop [24] are some of the well-known configurations. Moreover, optical solutions are possible by adding components such as optical filters [25][26][27] and optical amplifiers [28,29] or by adjusting the optical link to achieve an optical gain [30]. These are already used to improve the stabilization of the OEO.…”

High-frequency signal oscillators are devices needed for a variety of scientific disciplines. One of their fundamental requirements is low phase noise in the micro- and millimeter wave ranges. The opto-electronic oscillator (OEO) is a good candidate for this, as it is capable of generating a signal with very low phase noise in the micro- and millimeter wave ranges. The OEO consists of an optical resonator with electrical feedback components. The optical components form a delay line, which has the advantage that the phase noise is independent of the oscillator’s frequency. Furthermore, by using a long delay line, the phase noise characteristics of the oscillator are improved. This makes it possible to widen the range of possible OEO applications. In this paper we have reviewed the state of the art for OEOs and micro- and millimeter wave signal generation as well as new developments for OEOs and the use of OEOs in a variety of applications. In addition, a possible implementation of a centralized OEO signal distribution as a local oscillator for a 5G radio access network (RAN) is demonstrated.

“…Recently, photonic technology has been widely used for microwave/optical signal generation, processing and transmission [2], serving as one promising solution to overcome the bandwidth limitation. Therefore, a number of approaches on photonics-assisted microwave frequency measurement or instantaneous frequency measurement (IFM), have been realized by monitoring microwave powers [3] or optical powers [4,5].…”

A photonic approach to microwave frequency measurement under large-signal modulation is proposed and demonstrated experimentally. Under the case of large-signal modulation, the microwave signal with its frequency to be measured is applied to externally modulate the optical carrier inside a phase modulator. Then the phase-modulated optical signal is equally divided and sent to two dispersive elements with different chromatic dispersions (e.g., single mode fiber), to perform phase modulation to intensity modulation (PM-IM) conversion. Subsequently, the fundamental component and the DC component at the output of photodetector (PD) are measured and used to establish a relationship between the microwave frequency and the power ratio, while the large modulation index arising from large-signal modulation is completely removed. Therefore, a microwave power-independent microwave frequency measurement has been realized under large-signal modulation. The proposed approach is then verified by a proof-of-concept experiment. Within the range of 7-13GHz, measurement errors less than ±0.3GHz are achieved.

“…Recently, OEO has not only been used to generate single-frequency microwave waveform, but also arbitrary waveform such as arbitrarily phase coded, chirped and triangular microwave waveforms and high repetition-rate optical pulse train. The key feature of an OEO-based AWG is that an external waveform generator is not required which makes that waveform generator compact and low cost [66][67][68].…”

This paper reviews recent progresses on optical arbitrary waveform generation (AWG) techniques, which could be used to break the speed and bandwidth bottlenecks of electronics technologies for waveform generation. The main enabling techniques for optically generating optical and microwave waveforms are introduced and reviewed in this paper, such as wavelength-to-time mapping techniques, space-to-time mapping techniques, temporal pulse shaping (TPS) system, optoelectronics oscillator (OEO), programmable optical filters, optical differentiator and integrator and versatile electro-optic modulation implementations. The main advantages and challenges of these optical AWG techniques are also discussed.
