Abstract

We propose antireflection coatings at the entrance and exit of arbitrary waveguide bends with graded index photonic crystals. The implementation of the proposed system is validated within the lowest band. The finite element method is employed to simulate the electromagnetic wave propagation of the designed device and analyze the influence of surface termination on transmission efficiency. The results show that the proposed system using antireflection structures exhibits a high-efficiency transmission performance. In addition, the incident waves can smoothly travel through the waveguide bends and keep their original field patterns.
