説明
<jats:p>Measurements of temporal profile of a femtosecond laser pulse propagating through a one-dimensional metallic plasmonic crystal show that the pulses are severely distorted when they excite surface plasmon (SP) resonances. Significant differences in the nature of the distortion are found for the SP states at the two edges of the SP band gap, reflecting sharp contrasts in their lifetime.</jats:p>
