The appropriate technique for coupling light efficiently from the conventional silica waveguide (SWG) entrance and exit of a photonic crystal slab waveguide (PCSWG) in a square lattice of dielectric rods is determined by calculation using the two-dimensional (2D) and three-dimensional (3D) finite-difference time-domain method. Four types of taper structure as the interface between SWG and PCSWG have been investigated. Coupling efficiency is found to be highly sensitive to the taper structure, defect rod configuration, and slab thickness. We find that when the type D tapered structure with a pair of larger defect rods, which is more flexible during fabrication, is placed between input/output SWG and PCSWG, if alters the mode properties of the guide mode so that mode matching can be achieved by determining the optimum defect configurations. Also, detailed computations of the 2D device and 3D slab version are given.
