| 英文摘要 | The dipole mode in triangular photonic crystal single defect cavity is degenerate. by deforming the lattice in photonic crystal we can obtain non-degenerate dipole modes. lattice deforming in the whole photonic crystal destroys the characteristic of symmetry, so the distribution of the electromagnetic field is affected and the polarization of the electromagnetic field is also changed. lattice deforming divides the degenerate dipole mode into the x-dipole mode and the y-dipole mode. it is found that the non-degenerate modes have better properties of polarization. so the high polarization and single dipole mode photonic crystal laser can be achieved by deforming the lattice of photonic crystal. in this paper, we simulated the cavity in photonic crystal slab and mainly calculated the quality factor of x-dipole mode under different deforming conditions and with different filling factors. the properties of polarization of x-dipole and y-dipole modes are also calculated. it is found that the ratio of intensities of e(x) to e(y) in x-dipole mode and that of e(y) to e(x) in y-dipole mode are 44 and 27, respectively. |
