摘要

Abstract

Analog-to-digital converters (ADCs) must be high speed

broadband

and accurate for the development of modern information systems

such as radar

imaging

and communications systems; photonic technologies are regarded as promising technologies for realizing these advanced requirements. Here

we present a deep-learning-powered photonic ADC architecture that simultaneously exploits the advantages of electronics and photonics and overcomes the bottlenecks of the two technologies

thereby overcoming the ADC tradeoff among speed

bandwidth

and accuracy. Via supervised training

the adopted deep neural networks learn the patterns of photonic system defects and recover the distorted data

thereby maintaining the high quality of the electronic quantized data succinctly and adaptively. The numerical and experimental results demonstrate that the proposed architecture outperforms state-of-the-art ADCs with developable high throughput; hence

deep learning performs well in photonic ADC systems. We anticipate that the proposed architecture will inspire future high-performance photonic ADC design and provide opportunities for substantial performance enhancement for the next-generation information systems.
