Abstract
A two-dimensional (2D) square-lattice photonic crystal (PhC) based on a circular hollow dielectric cylinder and flat dielectric cylinders include a high-refractive-index dielectric cylinder and a low-refractive-index dielectric background, the PhC structure is formed by arranging unit cells in a square-lattice; one lattice constant of the square-lattice PhC is a; each unit cell includes a circular hollow dielectric cylinder and flat dielectric cylinders; and the circular hollow dielectric cylinder is connected to four flat dielectric cylinders; a width D of the flat dielectric cylinder is 0.01a to 0.2a, an outer diameter R of the circular hollow dielectric cylinder is 0.1a to 0.5a, and a ratio T of a difference between an inner diameter and an outer diameter of the circular hollow dielectric cylinder to the outer diameter of the circular hollow dielectric cylinder is 0.01 to 0.99.
