Abstract
We derive a light-intensity-dependent dielectric constant for gain medium based on the conventional rate equation model. A scattering-matrix method in conjunction with an efficient iteration procedure is proposed to simulate photonic crystal lasers (PCLs). The light output vs pumping (L-I) curve, lasing mode profile, and chirping effect of lasing wavelength can be calculated. We check our method in a 1D DBR laser and the L-I curve agrees well with results by the rate equation model. Our method can be extended to 3D systems. More complex 2D and 3D PCLs will be simulated in the future.
