标题： Real-time dynamics and cross-correlation gating spectroscopy of free-carrier Drude slow-light solitons

摘要： 光学孤子——在非线性和色散效应之间微妙平衡的稳定波——推动了超快光学和动力学领域的发展，其贡献涵盖了超连续谱生成和孤子分裂，到光学事件视界、霍金辐射和光学 rogue 波等。 在这里，我们研究在德鲁德模型自由载流子引起的非线性效应影响下，硅慢光光子带隙波导中的皮焦耳孤子动力学。 使用实时和单次放大的色散傅里叶变换光谱学，同时结合在飞焦耳灵敏度和飞秒分辨率下的高保真交叉相关频率分辨光学门技术，我们检查了孤子稳定性极限，包括自由载流子四次方慢光尺度和加速的孤子动力学，以及德鲁德电子-空穴等离子体对切连科夫辐射和调制不稳定性的影响。 我们的实时单次和时间平均交叉相关测量与我们的详细理论建模相匹配，研究了皮焦耳级孤子上的减少群速度自由载流子动力学。 显示英文摘要

摘要： Optical solitons-stable waves balancing delicately between nonlinearities and dispersive effects-have advanced the field of ultrafast optics and dynamics, with contributions spanning supercontinuum generation and soliton fission, to optical event horizon, Hawking radiation, and optical rogue waves, amongst others. Here we investigate picojoule soliton dynamics in silicon slow-light photonic-bandgap waveguides under the influence of Drude-modeled free-carrier induced nonlinear effects. Using real-time and single shot amplified dispersive Fourier transform spectroscopy simultaneously with high-fidelity cross-correlation frequency-resolved optical gating at femtojoule sensitivity and femtosecond resolution, we examine the soliton stability limits, the soliton dynamics including free-carrier quartic slow-light scaling and acceleration, and the Drude electron-hole-plasma induced perturbations on Cherenkov radiation and modulation instability. Our real-time single shot and time-averaged cross-correlation measurements are matched with our detailed theoretical modeling, examining the reduced group velocity free-carrier kinetics on solitons at picojoule.
