论文摘要
在本文中，采用系统的方法来设计具有正折射和负折射之间边界的光子晶体，以增强晶体的折射率。使用数学技术将EFC工程的过程转变为无试版步骤的几乎机械过程。然后，通过添加具有倾斜边界的第二个光子晶体，进一步改善了设计的弹能操作特性。第一个晶体中的折射光束在第二光子晶体的斜界面上撞击，以体验Bloch波数的变化，甚至更大的折射角，从而使新型的超级分散性两步光学消除器发生。对于λ= [1474nm，1550nm]的输入光谱，获得了161度的梁发散。
In this paper, a systematic approach is employed to design a photonic crystal with a boundary between positive and negative refraction to boost the refractive properties of the crystal. Mathematical techniques are employed to turn the process of EFC engineering into a nearly mechanical process free of trial-and-error steps. The designed demultiplexers operational characteristics are then further improved by adding a second photonic crystal with an oblique boundary. The refracted beams in the first crystal impinge on an oblique interface of the second photonic crystal to experience a change in Bloch wavenumbers and even greater refraction angles so that a novel super-dispersive two-step optical demultiplexer is made. A beam divergence of 161 degrees is obtained for an input spectrum of λ= [1474nm, 1550nm].
