摘　　要：We propose a novel automatic phase-matching method for generating optical frequency combs using cascaded electrooptic modulators.By analyzing the power changes of different spectral lines,our method enables real-time monitoring and dynamic adjustment to achieve precise phase matching.Experiments have confirmed the fast phase matching and the adjustable spacing of a flat electro-optic frequency comb and its long-term stability.This method provides flexible and efficient light source solutions for optical communications,spectral analysis,and optical measurements.
