Photon analog-to-digital conversion system based on coupled photoelectric oscillator

The invention discloses a photon analog-to-digital conversion system based on a coupled photoelectric oscillator, and belongs to the technical field of optical communication information processing. The system comprises a coupled photoelectric oscillator, an intensity modulator, a first-stage dual-output modulator, two second-stage dual-output modulators, four photoelectric detectors, four electricanalog-to-digital converters, a first-stage divide-by-2 frequency divider, a second-stage divide-by-2 frequency divider and a plurality of adjustable delay lines. According to the invention, the coupled photoelectric oscillator is introduced into the system, and compared with a traditional photon analog-to-digital conversion system, the photon analog-to-digital conversion system can generate synchronous microwave signals and optical pulse signals, the microwave signals have ultralow phase noise, the optical pulse signals have the advantages of high repetition frequency, short pulse width andsmall time jitter, higher
