摘要

在强群速度色散(GVD)介质中，由于相速度不同，信号波形在响应不同频率时会产生畸变。然而，受因果关系的限制，强分散往往伴随着高损失。由于欺骗表面等离子激元(SPPs)的群速度作为频率的函数丰富，且易于通过尺寸和几何形状进行操纵，因此通过工程设计，使SPPs的色散特性在一定频带内同时满足强色散群速度和高效反射率，从而实现高效实时反射波形调制器。

High-Efficiency Real-Time Reflective Waveform Modulator Based on Dispersion Engineering of Spoof Surface Plasmon Polaritons

In strong group velocity dispersion (GVD) medium, signal waveform will distort owing to different phase velocity with responding to different frequencies. Whereas, limited by causality, strong dispersion is always accompanied by high losses. Because group velocity as a function of frequency of spoof surface plasmon polaritons (SPPs) is rich and easy to be manipulated by the size and geometry, so by engineering the dispersion characteristics of SPPs strong dispersive group velocity and high-efficiency reflectivity will be satisfied at certain band simultaneously, in order to realize high-efficiency real-time reflective waveform modulator.
