A resonance system of an optoelectronic oscillator based on a transmission-type planar optical disk microcavity [PDF]
Компьютерная оптика, 2018 It is noted that the best technical characteristics of optoelectronic microwave self-oscillators (OESO) are reached in schemes employing high-Q optical microresonators (OMR) working in the traveling wave modes (TWM).

Hybrid-integrated wideband tunable optoelectronic oscillator
Optics Express, 2023 As a photonic-based microwave signal generation method, the optoelectronic oscillator (OEO) has the potential of meeting the increasing demand of practical applications for high frequency, broadband tunability and ultra-low phase noise. However, conventional OEO systems implemented with discrete optoelectronic devices have a bulky size and low ...
