论文摘要
光子晶体的主要用途是设计状态的光子密度，从而控制光耦合。从理论上讲，我们表明，紧张的2D光子晶体可以产生人工电磁场和高度退化的Landau水平。由于未通过紧密结合描述光子晶体，因此我们采用了全波方程的多尺度扩展。使用数值模拟，我们观察到分散式Landau水平，我们显示的伪电场可以通过工程来扁平。人造田地为基质纳米光系统产生设计原理。
The principal use of photonic crystals is to engineer the photonic density of states, which controls light-matter coupling. We theoretically show that strained 2D photonic crystals can generate artificial electromagnetic fields and highly degenerate Landau levels. Since photonic crystals are not described by tight-binding, we employ a multiscale expansion of the full wave equation. Using numerical simulations, we observe dispersive Landau levels which we show can be flattened by engineering a pseudoelectric field. Artificial fields yield a design principle for aperiodic nanophotonic systems.
