论文摘要
从理论上讲，我们研究了由光子晶体支持的引导Bloch表面波（BSW）中的光传播。我们证明，仅通过对多层的正确设计就可以获得光子带隙以用于两种光极化，就可以实现低传播损失。我们提出了一种基于傅立叶分析的设计策略，该策略允许人们获得在可见光谱范围内运行的结构，从而获得低至5 dB/km的固有损失。这些结果阐明了指导BSW中照明传播的限制因素，并代表了开发基于BSW的集成光学平台的基本步骤。
We theoretically study light propagation in guided Bloch surface waves (BSWs) supported by photonic crystal ridges. We demonstrate that low propagation losses can be achieved just by a proper design of the multilayer to obtain photonic band gaps for both light polarizations. We present a design strategy based on a Fourier analysis that allows one to obtain intrinsic losses as low as 5 dB/km for a structure operating in the visible spectral range. These results clarify the limiting factors to light propagation in guided BSWs and represent a fundamental step towards the development of BSW-based integrated optical platforms.
