中文摘要	a theoretical analysis has been performed by means of the plane-wave expansion method to examine the dispersion properties of photons at high symmetry points of an inp based two-dimensional photonic crystal with square lattice. the q factors are compared qualitatively. the mechanism of surface-emitting is due to the photon manipulation by periodic dielectric materials in terms of bragg diffraction. a surface-emitting photonic crystal resonator is designed based on the phenomenon of slow light. photonic crystal slabs with different unit cells are utilized in the simulation. the results indicate that the change of the air holes can affect the polarization property of the modes. so we can find a way to improve the polarization by reducing the symmetry of the structure.
