本文报道了亚波长绝缘体上硅波导中飞秒脉冲群速度色散和非线性啁啾的时域测量结果。我们观察到，在一个关键的输入功率水平，这两个效应相互补偿导致孤子的形成。在波导内部几瓦的峰值功率下观察到基本光孤子的形成。干涉互相关迹线揭示了孤子脉冲的压缩，而光谱测量显示孤子发射到正常群速度色散的波长范围内的明显色散（切伦科夫）波。(C)2010年美国光学学会
We report time domain measurements of the group-velocity-dispersion-induced and nonlinearity-induced chirping of femtosecond pulses in subwavelength silicon-on-insulator waveguides. We observe that at a critical input power level, these two effects compensate each other leading to soliton formation. Formation of the fundamental optical soliton is observed at a peak power of a few Watts inside the waveguide. Interferometric cross-correlation traces reveal compression of the soliton pulses, while spectral measurements show pronounced dispersive (Cherenkov) waves emitted by solitons into the wavelength range of normal group velocity dispersion.
