Merging of optoelectronic techniques for microwave signal generation [PDF]
, 2007 This paper describes some recent evolutions about optical generation of microwave signals. Among these, multiloop ring oscillator and harmonic generation allow both rise in frequency and wide tunability. Besides, using microresonators and optical sources

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 ...

Parity-time symmetry in wavelength space within a single spatial resonator
Nature Communications, 2020 Most conventional PT-symmetric systems contain two physically separated modes. Here the authors proposed a PT-symmetric microwave optoelectronic oscillator, where the gain and loss modes are confined in a single spatial resonator, resulting in an ...
