Wider Bandwidth and Higher Transmission for 60o Photonic Crystal Waveguide Bends

In this paper, a 6f waveguide bend in a twodinensional photonic crystal (PC) is designed. The structure used is a 2D PC with air holes in a triangular lattice Also, TE modes are considered in the single mode frequency region. The frequency characteristics of the bend can be improved by changing the geometrical parameters. Using this method, the bandwidth of the bend can surpass the values previously reported in the literature. The results show that wider bandwidth and higher transmission can be obtained.
