Advances in optoelectronic oscillators
SPIE Proceedings, 2016Optoelectronic oscillators are used for a wide variety of applications in microwave photonics. We here report the latest advances in this technology from our research group, with emphasis on the analysis of phase noise performance. We present a stochastic modelling approach for phase noise performance analysis of optoelectronic oscillators based on ...

Subharmonic Optoelectronic Oscillator
IEEE Photonics Technology Letters, 2008I propose and demonstrate a subharmonic optoelectronic oscillator (SH-OEO), which contains a frequency divider in the feedback loop and performs optical clock division, prescaled optical clock recovery, and optical time-division demultiplexing in the absence of subharmonic tones in the input signals. Also, I propose a scheme that achieves divide-by-two

An integrated optoelectronic oscillator
2017 International Topical Meeting on Microwave Photonics (MWP), 2017An integrated optoelectronic Oscillator (IOEO) which combines the integrated technologies of photonics and electronics has been developed. All of the necessary elements (for example, laser, photo-detector, electrical amplifier, electrical filter, etc.) have been assembled on a print circuit board (PCB) within size of 5∗6 cm.

Dual-frequency tunable optoelectronic oscillator
Asia Communications and Photonics Conference/International Conference on Information Photonics and Optical Communications 2020 (ACP/IPOC), 2020A dual-frequency tunable optoelectronic oscillator based on the nonlinear effect of an amplifier is proposed and experimentally demonstrated. In the experiment, a dual-frequency signal with tuning ranges of 6.68-10.6 GHz and 20.04-31.9 GHz is generated.

Performance evaluation of an optoelectronic oscillator
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2000Phase noise measurements of an optoelectronic oscillator (OEO) at frequencies less than 10 Ha from the carrier (10.6 GHz) as well as the measured Allan variance are presented for the first time. The system has a measured single-side-band (SSB) phase-noise of -123 dB/Hz at 10 kHz from the carrier and a sigma(y)(tau)=10(-10) for an integration time ...

Physical Review E, 2018
We present a detailed study of instabilities arising in optoelectronic oscillators with a single narrow-band time-delayed feedback loop. Such optoelectronic oscillators produce periodic solutions and may be useful as high-purity signal generators, but ...

An Etalon based Optoelectronic Oscillator
Conference on Lasers and Electro-Optics 2010, 2010A 10.287 GHz optoelectronic oscillator is demonstrated which uses a 1000 finesse Fabry-Perot etalon as the mode selector instead of an RF filter. The new OEO has higher RF frequency stability and lower phase noise.

Optoelectronic oscillator for photonic systems
IEEE Journal of Quantum Electronics, 1996We describe a novel photonic oscillator that converts continuous-light energy into stable and spectrally pure microwave signals. This optoelectronic oscillator (OEO) consists of a pump laser and a feedback circuit including an intensity modulator, an optical-fiber delay line, a photodetector an amplifier, and a filter. We present the results of a quasi-
