论文摘要
在本文中，我们提出了六角形晶格的不对称分布，以实现接近零组的速度，而组延迟为负。这项研究报告了连续的几何扰动对光子带图的影响，从而对相位速度，组速度和有效折射率的影响。我们提供了一种有前途的方法，用于修改光子带图获取外来色散图。随着这种从E到L带的宽带，它包裹着近乎零速度的光脉冲横穿，足以将其应用于各种光基设备中。
In this paper, we propose an asymmetric distribution of a hexagonal lattice for achieving near-zero group velocity with negative group delay. This study reports the effect of the continuous geometric perturbation on the photonic band diagram and consequently its impact on phase velocity, group velocity, and effective refractive index. We provide a promising method for modifying the photonic band diagram for obtaining an exotic dispersion diagram. With this obtaining a broadband spanning from E to L band that envelop of light pulse traverse with almost zero velocity is promising enough to apply it in a wide variety of light-based devices.
