时态光学孤子由于其有趣的物理特性以及在超快光学和超连续谱产生中的应用而成为深入研究的主题。传统的亮光学孤子是由反常群速度色散和自相位调制的相互作用产生的。在这里，我们通过实验证明了一类亮孤子纯粹由负四阶色散和自相位调制的相互作用产生，即使对于正常的群速度色散也可能发生。我们提供了基本纯四次孤子的保形传播和平坦时间相位以及高阶纯四次孤子的周期性调制传播的实验和数值证据。我们推导出基本纯四次孤子的近似形状，并发现它是令人惊讶的高斯形状，与我们的实验观察结果表现出极好的一致性。我们的发现通过精确的色散工程实现，可以在通信、频率梳和超快激光器中找到应用。
Temporal optical solitons have been the subject of intense research due to their intriguing physics and applications in ultrafast optics and supercontinuum generation. Conventional bright optical solitons result from the interaction of anomalous group-velocity dispersion and self-phase modulation. Here we experimentally demonstrate a class of bright soliton arising purely from the interaction of negative fourth-order dispersion and self-phase modulation, which can occur even for normal group-velocity dispersion. We provide experimental and numerical evidence of shape-preserving propagation and flat temporal phase for the fundamental pure-quartic soliton and periodically modulated propagation for the higher-order pure-quartic solitons. We derive the approximate shape of the fundamental pure-quartic soliton and discover that is surprisingly Gaussian, exhibiting excellent agreement with our experimental observations. Our discovery, enabled by precise dispersion engineering, could find applications in communications, frequency combs and ultrafast lasers.
