The measured dispersion of a low-loss, hollow-core photonic band-gap fiber is anomalous throughout most of the transmission band, and its variation with wavelength is large compared with that of a conventional step-index fiber. For an air-filled fiber, femtosecond self-frequency--shifted fundamental solitons with peak powers greater than 2megawatts can be supported. For Xe-filled fibers, nonfrequency-shifted temporal solitons with peak powers greater than 5.5 megawatts can be generated, representing an increase in the power that can be propagated in an optical fiber of two orders of magnitude. The results demonstrate a unique capability to deliver high-power pulses in a single spatial mode over distances exceeding 200 meters.
低损耗空芯光子带隙光纤在大部分传输波段测得的色散是反常的，与传统阶跃折射率光纤相比，其随波长的变化很大。对于空气填充光纤，可以支持峰值功率大于2兆瓦的飞秒自频移基孤子。对于氙气填充光纤，可以产生峰值功率大于5.5兆瓦的非频移时间孤子，这意味着在光纤中能够传播的功率增加了两个数量级。结果表明，该光纤具有在超过200米的距离上以单空间模式传输高功率脉冲的独特能力。
