Abstract

Diffraction properties of a two-dimensional photonic crystal is presented. Diffraction experiments are carried out using a ring beam and the relevant experimental designs are shown. Drastic ring deformations are observed after diffractions, for different kind of ring beams. The diffraction properties are analyzed using the equ-frequency surface and the photonic band structure of a photonic crystal. The paper also describes the fundamental difference between the diffraction properties of photonic crystals with weak and finite modulation in their dielectric property.
