Negative Propagation Effects in Two-Dimensional Silicon Photonic Crystals

Negative Propagation Effects in Two-Dimensional Silicon Photonic Crystals

We demonstrated negative refraction effects of light propagating in two-dimensional square and hexagonal-lattice silicon photonic crystals (PhCs). The plane wave expansion method was used to solve the complex eigenvalue problems, as well as to find dispersion curves and equal-frequency contour (EFC)...
