We present a flexible method that can calculate Bloch modes, complex band structures, and impedances of two-dimensional photonic crystals from scattering data produced by widely available numerical tools. The method ...

Photonic crystals offer the opportunity to design ultra-compact optical devices. Here we consider the "folded directional coupler," which combines elements of a directional coupler and a Fabry-Perot interferometer. This ...

An essential component in the design and fabrication of large scale integrated optical circuits is the photonic crystal (PC) waveguide, a device which can channel light, with minimal loss, around tight bends using band ...
