实验研究了光纤系统中各种离散时间孤子的形成和稳定传输。脉冲与时间周期势和散焦非线性相互作用，形成间隙孤子和非线性截断布洛赫波。多脉冲孤子的缺陷，以及新的结构组成的一个强大的孤子骑在一个较弱的截断非线性布洛赫波的传播超过11耦合长度。所有的脉冲结构的非线性动力学监测在整个传播距离，提供了详细的洞察孤子动力学。
We experimentally demonstrate the formation and stable propagation of various types of discrete temporal solitons in an optical fiber system. Pulses interacting with a time-periodic potential and defocusing nonlinearity are shown to form gap solitons and nonlinear truncated Bloch waves. Multi-pulse solitons with defects, as well as novel structures composed of a strong soliton riding on a weaker truncated nonlinear Bloch wave are shown to propagate over up to eleven coupling lengths. The nonlinear dynamics of all pulse structures is monitored over the full propagation distance which provides detailed insight into the soliton dynamics.
