“…Starting with the EAM-OEO, the same system can be used to recover the clock of a 10 or 40 GHz RZ digital data signal [70]. The optical signal is injected into the OEO cavity and both an electrical and optical clock are recovered.…”

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.

“…For 3R regeneration, clock signal extraction from a distorted data signal is needed, and the extracted clock signal must exhibit lower timing jitter than the degraded data signal. CR has been performed by various techniques, e.g., by a self-pulsating DFB laser, a mode-locked laser, and an optical PLL; see, e.g., [36]. In order for a recovered clock signal to have less jitter than the input signal, the jitter of the free-running local oscillator must be less than that of the input signal [38].…”

Abstract-A detailed theoretical analysis of a clock-recovery (CR) scheme based on an optoelectronic phase-locked loop is presented. The analysis emphasizes the phase noise performance, taking into account the noise of the input data signal, the local voltage-controlled oscillator (VCO), and the laser employed in the loop. The effects of loop time delay and the laser transfer function are included in the stochastic differential equations describing the system, and a detailed timing jitter analysis of this type of optoelectronic CR for high-speed optical-time-division-multiplexing systems is performed. It is shown that a large loop length results in a higher timing jitter of the recovered clock signal. The impact of the loop length on the clock signal jitter can be reduced by using a low-noise VCO and a low loop filter bandwidth. Using the model, the timing jitter of the recovered optical and electrical clock signal can be evaluated. We numerically investigate the timing jitter requirements for combined electrical/optical local oscillators, in order for the recovered clock signal to have less jitter than that of the input signal. The timing jitter requirements for the free-running laser and the VCO are more relaxed for the extracted optical clock (lasers's output) signal.Index Terms-Clock recovery (CR), optical time division multiplexing (OTDM), optoelectronic phase-locked loop (OPLL), oscillator noise, phase noise, stochastic differential equations, time delay, timing jitter.

“…Because of the relative simplicity of the mathematical model and the good quantitative agreement with experiments, an OEO is a particularly desirable set up if we wish to explore delay-induced instabilities in the laboratory [36]. These instabilities and their control have led to new applications for secure optical communication [37], radars requiring ultra-pure sources of light [38][39][40], and neuromorphic computing [41,42].…”

Two distinct bifurcation routes for delayed optoelectronic oscillators

2017

We investigate the coexistence of low-and high-frequency oscillations in a delayed optoelectronic oscillator. We identify two nearby Hopf bifurcation points exhibiting low and high frequencies and demonstrate analytically how they lead to stable solutions. We then show numerically that these two branches of solutions undergo higher order instabilities as the feedback rate is increased but remain separated in the bifurcation diagram. The two bifurcation routes can be followed independently by either progressively increasing or decreasing the bifurcation parameter.
