摘要
The present invention discloses a 2D square-lattice PhC based on cross rods and rotated hollow square rods, comprising a high-refractive-index dielectric rod, a cross plate dielectric rod and a low-refractive-index background dielectric rod; the unit cell of the square-lattice PhC includes a high-refractive-index rotated hollow square rod, a cross plate dielectric rod and a background dielectric; the hollow square rod has an outer contour which is a first rotated square rod with the rotated angle α of 45° to 65° and the side length b of 0.6 a to 0.75 a, and a hollow part with a cross section being a second rotated square rod with the rotated angle β of 25° to 50° and the side length c of 0.33 a to 0.5 a; the first rotated square rod is connected with the cross plate dielectric rod, plate dielectric rods of which in the horizontal and vertical directions have different widths.
