利用反向耦合谐振腔诱导透明(Inverted-Crit)系统中可控的反常色散，实验研究了峰值截断的高斯型时间脉冲的传输。在输出端口处再生了与高斯脉冲相关的平滑脉冲峰值，即使在输入脉冲没有峰值的情况下也没有任何变形。这种倒CRT峰值的一个独特特征是，该峰值没有衰减(或放大)，因此表现出与截断前的原始输入脉冲相同的强度。我们讨论了倒CRT中的脉冲传播与正常CRIT系统中的脉冲传播的关系，即慢光系统中的脉冲传播，在该系统中，即使入射脉冲有峰值，输出脉冲也没有峰值。
Using controllable anomalous dispersion in an inverted coupled-resonator-induced transparency (inverted-CRIT) system, we experimentally explored the propagation of a peak-truncated Gaussian-shaped temporal pulse. A smooth pulse peak related to the Gaussian pulse was regenerated at the output port without any deformation, even when the input pulse lacked the peak. A unique feature of this inverted-CRIT peak is that the peak is not attenuated (or amplified), and thus exhibits an intensity identical to that of the original input pulse before truncation. We discuss pulse propagation in inverted-CRIT in relation to pulse propagation in a normal-CRIT system, i.e., a slow-light system, in which the output pulse lacks a peak even when the incident pulse has one.
