Spatial characteristics of radiation of 1D photonic crystal laser

We present the results of calculations of the spectral and spatial characteristics of finite length 1D PC with air-glassdoped layers. For these calculations we used the transfer matrix formalism. We present also the results of calculation accounting nonlinear deformation of the field distribution along the structure due to gain and refraction index saturation. The results of calculations of laser power are presented on the dependence from gain and from angle of propagation. The lazing optimum condition is determined.
