我们报告了波导型光学频率梳发生器（WG-OFCG）的调制特性，该发生器具有紧凑、高调制指数和损耗的优点。讨论了调制指数超过2 pi时产生的光频梳(OFC)的特性。采用外腔激光器作为本地振荡器，通过光外差法测量调制边带的功率，测量了WG-OFCG的调制指数对高达40 GHz的调制频率的依赖性。讨论了 OFC 在与自由光谱范围 (FSR) 整数倍失谐的调制频率下的生成跨度。
We report the modulation characteristics of a waveguide-type optical frequency comb generator (WG-OFCG) with the advantages of compactness, high modulation index and loss. driving power, The characteristics of the optical frequency comb (OFC) generated when the modulation index exceeds 2 pi are discussed. The power of the modulation sidebands was measured by the optical heterodyne method with an external-cavity laser as a local oscillator, The dependence of the modulation index of the WG-OFCG on the modulation frequency up to 40 GHz was measured. The generation span of the OFC at the modulation frequency detuned from an integer multiple of the free spectral range (FSR) is discussed.
