Spontaneous emission lifetime distribution in the basic unit cell or on a plane of the excited quantum dots embedded in woodpile photonics crystals with low refractive index contrast are investigated. It is found that the spontaneous emission lifetime distribution strongly depends on the position and transition frequency of the emitters, and has the same symmetry as that of the unit cell. Furthermore, it is revealed that the polarization orientation of the emitters has significant influence on the lifetime distribution. These results may be supplied in probing the lifetime distribution or orientation-dependent local density of states in future experiments.
