摘要

对基于频率梳源的10 GHz频率光导辅助模数转换器的可行性进行了数值研究。研究发现，有效比特数(ENOB)随输入射频频率的增加而单调减小。然而，我们发现，在50 GHz的奈奎斯特采样率下，仅使用10个WDM信道就可以实现4的ENOB。结果表明，在不影响ADC性能的前提下，采用高重复频率的脉冲源可以简化系统。

A photonic assisted analog-to-digital converter (p-ADC) based on a 10 GHz frequency comb source

The feasibility of a photonic-assisted analog-to-digital converter based on a frequency comb source operating at 10 GHz is numerically investigated. It is found that the effective number of bits (ENOB) monotonically decreases with the input RF frequencies. Nevertheless, it is found that ENOB of 4 can be achieved at the Nyquist sampling rate of 50 GHz using only 10 WDM channels. The results demonstrate that the system can be simplified by employing a high repetition rate pulsed source without greatly affecting the ADC performance.
