%X The spatial profile and its influence on the lasing threshold of defect modes are investigated by use of the finite-difference time-domain (FDTD) method and the transfer matrix method (TMM) in a one-dimensional photonic crystal through the two effective parameters,the localization length and the mode area.The results indicate that the lasing threshold becomes lower if the localization length and mode area get smaller.The localization length and the mode area of defect modes can be effectively modified to decrease the lasing threshold by adjusting parameters such as the defect width, the ratio of optical thickness and the ratio of refractive index.
