Flexible photonic crystal waveguide branches with arbitrary branching angles.
A fundamental Y branch based on a flexible photonic crystal waveguide is presented. By combining this fundamental Y branch with flexible waveguides, flexible waveguide branches with arbitrary branching angles are constructed. Numerical simulations of these branches indicate that without any structural optimization, near-complete transmission is observed within a wide frequency band. Owing to their unique flexibility, these waveguide branches are expected to be applied to high-density photonic integrated circuits after further research.
