光子模数转换技术被认为是一种很有前景的选择，可以通过消除孔径抖动的瓶颈，将模数转换器 (ADC) 的性能提升到新的水平。在这项工作中，我们回顾了光子 ADC 的一些重要方法，并回顾了该领域的最新发展。我们考虑一种特殊的光子 ADC 转换方案，该方案使用光学采样、波长解复用和电子数字化；该方案的一个重要优点是它可以作为电子-光子集成电路在硅芯片上实现。我们分析了通过该方案可以实现的 ADC 性能的重要基本和实际限制。
Photonic analog-to-digital conversion technology is considered a promising option to extend the performance of analog-to-digital converters (ADCs) to new levels by eliminating the bottleneck of aperture jitter. In this work, we review some important approaches to photonic ADCs and review recent developments in the field. We consider one particular scheme for photonic ADC conversion which uses optical sampling, wavelength demultiplexing, and electronic digitization; an important advantage of this scheme is that it can be implemented on a silicon chip as an electronic-photonic integrated circuit. We analyze important fundamental and practical limits to ADC performance which can be achieved with this scheme.
