AbstractWireless communication are becoming as a part of human life. If we want to achieve the efficient and affordable communication in wireless technology in optical domain, stable signal and ultra-low phase noise is required. Optoelectronic oscillator is based on converting continues light energy in stable and low phase noise, high-quality (Q) factor is used in wireless communication. If quality factor is low, then the oscillation dies out rapidly. Delay line is used provided higher-quality factor that is used. There are numerous techniques for the photonic generation of microwave signal with high time-bandwidth product and low phase noise. Optoelectronic oscillator (OEO) based generation techniques have been found one of the most interesting technique since last three decades. This approach provides very high frequency microwave signal with lowest possible phase noise. OEO has been designed with miscellaneous architecture by introducing different optical dispersive components such as optical fiber, chirped fiber Bragg grating, polarization modulator, and ring resonator. In this paper, numerous techniques for the design of OEO are reviewed and well demonstrated. There are interesting configurations with substantial improvement in phase noise and frequency of the microwave signals generated. MATLAB simulation has been used for the verification of result explained in this technique.

Abstract Gain-parameter-dependent transfer functions and phase-noise performances in a mode-locked Yb-doped fiber laser are measured in this study. It is discovered that the corner frequency in the amplitude and phase domains is determined by the absorption coefficient of the gain fiber, when the total absorption and other cavity parameters are fixed. This shows that an oscillator using gain fiber with higher dopant concentration accumulates more phase noise. Furthermore, we present net cavity dispersion-dependent transfer functions to verify the effect of dispersion management on the frequency response. We derive a guideline for optimizing mode-locked fiber laser design to achieve low phase noise and timing jitter.

An optoelectronic oscillator (OEO) is an optoelectronic hybrid oscillator which utilizes ultra-low loss fiber as an electro-magnetic energy storage element, overcoming the limits of traditional microwave oscillators in phase noise performance. Due to their ability to generate ultra-low phase noise microwave signal, optoelectronic oscillators have attracted considerable attentions and are becoming one of the most promising and powerful microwave signal sources. In this paper, we briefly introduce the operation principle and discuss current research on frequency stability and spurious suppression of optoelectronic oscillators.
