摘要
ADC广泛应用于手持设备, 以及**等领域。电ADC受限于时钟抖动和比较器模糊等关键指标, 性能基本接近理论极限, 提升空间有限。光ADC发挥了光子学的优势, 具有极大的带宽, 能实现远距离传输、远端处理, 是ADC发展的理想方向。光ADC能够很好地突破电ADC理论上的极限, 因此引起广泛关注。利用时间-波长交织、时间拉伸原理进行了光ADC的开发研究, 制做了高速光ADC样机, 进行了实验, 并分享了各项技术的细节。此外, 硅光集成技术将为光ADC技术打开新的窗口。
Abstract
The theoretical limit, with limited room for improvement, photonic analog-to-digital converter (PADC) can make full use of the advantages of photonics, such as ultrahigh speed and low timing jitter. It may find wide applications in broadband signal processing, long-distance transmission, remote processing for communications systems. So PADC is the ideal direction of development. Time-wavelength interleaving and time-stretch are two typical technologies for PADCs. This presentation talks about their principle, key issues and implementation methods. Recent advance and future development will also be introduced. In this report, a prototype of high-speed optical ADC was made to carry out experiments, and details of various technologies were shared. In addition, silicon optical integration technology will open a new window for optical ADC technology.
