Abstract :
2 and 3D Finite Difference Time Domain (FDTD) simulations and measurements of a hexagonal lattice 2D photonic crystal with holes having taper angles in the region of 3 to 7 degrees are performed. The results show a smoothing of band edges and increased losses. Reasonably good agreement between measured and modelled results is obtained.
