Summary: In this study, a low phase noise and high side-mode suppression ratio self-injection-locked OEO based on frequency conversion filtering was proposed. The influence of the phase noise of the external microwave source on the proposed OEO and the conventional injection-locked OEO was theoretically and experimentally investigated. The results showed that the proposed OEO was less sensitive to the phase noise of the external microwave source compared to the conventional injection-locked OEO.

Summary: We propose an analytically tractable model to simulate the effects of noise and jitter on the use of optoelectronic oscillators delivering optical square waves as an optical binary bit train. By computing parameters such as time-averaged signal, autocorrelation function, power spectral density, eye diagram, quality factor, bit-error rate, and Allan variance, this model serves as a simple tool for analysis and characterization in digital communications.

Summary: This paper analyzes various noise sources in delay-line optoelectronic oscillators (OEOs) with all-optical gain, highlighting the mutual conversion of amplitude and phase noises due to the non-linear time-variant dynamics. The correlation between amplitude and phase fluctuations affects the noise power spectrum density of the OEO output signal, leading to proposed methods for reducing this mutual conversion and improving phase noise performance.

Summary: A parity-time (PT) symmetric optoelectronic oscillator (OEO) with optical injection locking is proposed and demonstrated to generate single-mode microwave signals. The PT symmetry in the OEO is achieved by injection locking a distributed feedback laser and using a polarization-dependent Sagnac loop. Experimental results show that the OEO can achieve single-mode oscillation and generate the desired microwave signal under the broken PT symmetry condition.

Summary: The injection locking and pulling characteristics of a long-loop optoelectronic oscillator with a large number of closely-spaced longitudinal modes are analyzed. The locking and pulling performance depend on the initial frequency difference, voltage ratio, and Q factor of the free-running OEO. The phase noise performance depends on the locking range and the phase noise performance of both the free-running OEO and the injected microwave signal.

Summary: The study focused on using long loop delay in optoelectronic oscillator to achieve high Q factor, while exploring methods such as dual-loop, inject-locking structures, and feedforward technique to suppress narrowly spaced spurious modes. Results showed that the stability of spurious phase improved with the increase of fiber length, providing experimental evidence for potential spurious suppression methods in future work.

Summary: We propose and experimentally demonstrate a novel single-mode optoelectronic oscillator (OEO) based on phase conjugation with low frequency drift. The OEO achieves long-term frequency stabilization by employing photonic microwave phase-conjugate passive compensation. Experimental results show that the OEO significantly enhances the side mode suppression ratio (SMSR) of the RF signal and reduces the frequency drift after side mode suppression.

The influence of different laser parameters on the noise of the mode-locked regime was discussed in detail, shedding light on the noise characteristics in both continuous wave and mode-locked regimes.

It allows generation of extra tones through nonlinear four-wave mixing, and the frequency channel to which the input tone is converted can be chosen by adjusting the phase of the input signal.

Summary: In this study, spin noise spectroscopy experiments were performed on metastable helium atoms at room temperature. It was found that both circular and linear birefringence fluctuations were present, and two noise resonances were isolated at the Larmor frequency and at twice the Larmor frequency, depending on the orientation of the probe field polarization. The simple structure of metastable helium allowed for the probing and modeling of these peak behaviors in terms of circular and linear dichroisms and birefringences as well as spin oscillation modes.

Summary: We theoretically and numerically investigate the spin fluctuations induced in a thermal atomic ensemble by an external fluctuating uniaxial magnetic field, in the context of a standard spin noise spectroscopy (SNS) experiment. We show that additional spin noise is excited, which dramatically depends on the magnetic noise variance and bandwidth, as well as on the power of the probe light and its polarization direction. We develop an analytical perturbative model proving that this spin noise first emerges from the residual optical pumping in the medium, which is then converted into spin fluctuations by the magnetic noise and eventually detected using SNS. The system studied is a spin-1 system, which thus shows both Faraday rotation and ellipticity noises induced by the random magnetic fluctuations. The analytical model gives results in perfect agreement with the numerical simulations, with potential applications in future experimental characterization of stray field properties and their influence on spin dynamics.

Summary: Light-induced nonequilibrium spin-noise spectroscopy is demonstrated to be an efficient technique for probing the structure and coherent effects in a transition. Metastable helium is used to show a dual-peak structure in the spin-noise spectrum around the Larmor frequency. The split spectra can be well reproduced by both numerical and analytical models, enabling a direct measurement of light shifts and level structure.

Summary: The spin-noise mechanisms in a spin-1 system are studied in detail, both theoretically and experimentally. Different spin degrees of freedom result in spin-noise signals at the Larmor frequency or its second harmonic in the presence of a magnetic field. The dependence of the observed noise modes on the probed transition is shown to vary dramatically, depending on the Zeeman structure of the upper level of the transitions. These findings are successfully validated through measurements of spin-noise signals in an ensemble of metastable 4He at room temperature using three different transitions.
