摘要
A high-refractive-index single-compensation-scattering-cylinder right-angle waveguide of a cylindrical square lattice photonic crystal, being a photonic crystal formed by arranging a first dielectric cylinder having a high refractive index in a background dielectric having a low refractive index in a square lattice; one row and one column of the first dielectric cylinders having a high refractive index are removed from the photonic crystal to form a right-angle waveguide; a second dielectric cylinder having a high refractive index is arranged at a turn of the right-angle waveguide; and the second dielectric cylinder is a compensation scattering cylinder, and the first dielectric cylinders are high-refractive-index cylinders. The structure has an extremely low reflectivity and an extremely high transmission rate, thus facilitating an integration of a large-scale light path.
