Abstract
We provide what we believe to be the first experimental demonstration of linear Shockley-like surface states in an optically induced semi-infinite photonic superlattice. Such surface states appear only when the induced superlattice consisting of alternating strong and weak bonds is terminated properly at the surface. Our experimental results are in good agreement with our theoretical analysis.
摘要
我们提供了我们认为是在光诱导半无限光子超晶格中线性类肖克利表面态的首次实验证明。这种表面态仅在由交替的强键和弱键组成的诱导超晶格在表面适当终止时才会出现。我们的实验结果与我们的理论分析非常吻合。
