边界材料导光反射
Guiding and reflecting light by boundary material
摘要：
采用伪谱方法和时域有限差分模拟方法研究了有限高度和周围介质对一维和二维光子晶体光子晶体板的影响。示出的带隙被强烈修改的边界材料。作为一个应用，我们建议通过在板的顶部/下方图案化材料来反射和引导光。
英文摘要：
We study effects of finite height and surrounding material on photonic crystal slabs of one- and two-dimensional photonic crystals with a pseudo-spectral method and finite difference time domain simulation methods. The band gap is shown to be strongly modified by the boundary material. As an application we suggest reflection and guiding of light by patterning the material on top/below the slab.
