Theoretical Performance Evaluation of Spurious-Tone Suppression of a Multi-Loop Optoelectronic Oscillator Based on Closed-Loop Response Analysis [PDF]
Journal of Electromagnetic Engineering and Science, 2022 We theoretically evaluate the performance of spurious-tone suppression of a multi-loop optoelectronic oscillators (MOEO) based on closed-loop analysis. Spurious tones are unwanted oscillation signals due to the cavity effect of long-length optical fiber ...

Active mode-locking optoelectronic oscillator
Optics Express, 2020 The optoelectronic oscillator (OEO) has been widely investigated to generate ultra-pure single-frequency microwave signals. In this study, we propose and experimentally demonstrate an active mode-locking optoelectronic oscillator (AML-OEO), which can generate broadband microwave frequency comb (MFC) signals.
