WebAccurate bandstructure calculations are important for the design and analysis of photonic crystal devices. In this example, we will focus on how to use MODE' 2.5D FDTD propagation method to calculate the bandstructure of a slab photonic crystals device with a square and hexagonal lattice of holes. WebPhotonic Bandgap Photonic crystals are a powerful tool for the manipulation of optical dispersion and density of states. By utilizing the tools of lattice simulation, we can engineer photonic systems that have a variety of interesting band structures.
