Abstract We present a numerical analysis of the performance of three‐dimensional (3D) perfectly matched layer (PML) absorbing boundary conditions (ABCs) in a photonic crystal (PC) waveguide. This formulation dramatically reduces the reflections from the ends of the PC waveguide, leading to highly accurate transmittance and reflectance calculations for waveguide components. The 3D PC‐based PML ABC is demonstrated to give good results when used to analyze a 90° bend in a 3D PC waveguide. © 2004 Wiley Periodicals, Inc.
