Guiding and reflecting light by boundary material
arXiv:physics/0303051 · doi:10.1016/j.optcom.2004.09.023
Abstract
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.
