Abstract

We recently reported the fabrication of mid-infrared SOI photonic crystal slabs and confirmed the creation of the Dirac cone by the angle-resolved reflection spectroscopy. We found the Fano-like line shape, which made it difficult to tell the accurate eigenmode frequencies from the reflection peaks. In this presentation, we focus on the selection rule and the line shape of the reflection peaks. The phase shift of the transmitted and reflected waves will also be examined to clarify the correspondence between the eigenmode frequency and the line shape. The results will be compared with available experimental data.
