Effects of Timing Noise on Square-Wave Optoelectronic Oscillators
Applied Sciences, 2021 Optoelectronic oscillators produce microwave-modulated optical beams without external modulation. The most commonly studied types produces narrow-band output, i.e., optical output modulated by a sinusoid, in which case phase noise determines key figures ...

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 ...
