论文摘要
我们从理论上和实验上证明了以28 GHz,56 GHz和112 GHz的重复速率的高质量低占空比脉冲列车的产生。从连续波开始,我们通过应用正弦曲线和一组精心挑选的$π$ Shifts从时间和光谱域中的相位调制中受益。随着正常分散纤维的进一步非线性光谱膨胀,随后是分散补偿,我们达到了次秒持续时间和28 GHz时的占空比低至0.025。在两个或四个上方的一个组件中,光谱取消可以进一步加倍或四倍的重复率。
We theoretically and experimentally demonstrate the generation of high-quality low duty-cycle pulse trains at repetition rates of 28 GHz, 56 GHz and 112 GHz. Starting from a continuous wave we benefit from phase modulations in the temporal and spectral domains by applying a sinusoidal profile and a set of well-chosen $π$ shifts, respectively, to generate a train of modified besselons at doubled repetition rate. With further nonlinear spectral expansion in a normally dispersive fiber followed by dispersion compensation we achieve subpicosecond durations and a duty cycle as low as 0.025 at 28 GHz. Spectral cancelation of one component over two or four enables to further double or quadruple the repetition rate.
