Controllable repetition rate multiplication of micro-combs is demonstrated based on the perfect temporal Talbot effect. With third-order-dispersion being eliminated, the repetition rates of micro-combs can be precisely controlled with strong reconfigurability and compatibility. First, we show the fifth multiplication of the repetition rate with unaffected pulse width and shape in both simulation and experiment. By slightly changing fiber lengths, the repetition rate of a micro-comb is precisely increased by 10 times, 15 times, and 20 times, reaching even 980 GHz. The method is verified to be compatible with perfect crystal solitons in repetition rate multiplication. Combined together, larger repetition rates can be obtained. Besides, the perfect temporal Talbot effect can efficiently reduce both timing jitter and amplitude noise of input pulses, demonstrating the stable generation of high-quality pulses with flexible and high repetition rates. Furthermore, our scheme can avoid the trade-off between acquisition speed and temporal resolution in dual-comb synchronous optical sampling, which is quite useful for the ultrafast detection of transient response in unstable samples. This demonstration will lead to the possible realization of an integrated and flexible repetition rate multiplexer for soliton micro-combs and further promote the development of dual-comb applications and future terahertz science.

完美的时间Talbot效应辅助微梳的重复率乘法控制

基于完美的时间Talbot效应，证明了微梳子的可控重复率倍增。通过消除三阶色散，可以以强大的可重构性和兼容性精确控制微梳的重复率。首先，我们在仿真和实验中都显示了重复率与不受影响的脉冲宽度和形状的第五次相乘。通过稍微改变光纤的长度，微梳的重复率可以精确地提高10倍，15倍和20倍，甚至达到980 GHz。经验证，该方法与重复率乘法中的完美晶体孤子兼容。结合在一起，可以获得更大的重复率。此外，完美的时间Talbot效果可以有效降低输入脉冲的时序抖动和幅度噪声，展示了稳定灵活且重复率高的高质量脉冲的生成。此外，我们的方案可以避免双梳状同步光学采样中采集速度和时间分辨率之间的权衡，这对于在不稳定样品中超快速检测瞬态响应非常有用。该演示将可能实现用于孤子微梳的集成且灵活的重复率多路复用器，并进一步促进双梳应用和未来太赫兹科学的发展。这对于在不稳定样品中超快速检测瞬态响应非常有用。该演示将可能实现用于孤子微梳的集成且灵活的重复率多路复用器，并进一步促进双梳应用和未来太赫兹科学的发展。这对于在不稳定样品中超快速检测瞬态响应非常有用。该演示将可能实现用于孤子微梳的集成且灵活的重复率多路复用器，并进一步促进双梳应用和未来太赫兹科学的发展。
