Phase noise of electro-optic dual frequency combs

Abstract

Dual frequency combs are emerging as new tools for spectroscopy and signal processing. The relative phase noise of the tone pairs determines the performance (e.g. signal to noise ratio) of the detected spectral components. Although previous research has shown that the signal quality generally degrades with the increase of frequency difference between tone pairs, the scaling of the relative phase noise of dual frequency comb systems has not been fully characterized. In this paper, we model and characterize the …
