Paper Abstract

We use the multi-mode lasing equations of Haken to analyze the stationary state lasing patterns of two-dimensional dielectric microcavity lasers of different shape, including the circle and various smooth deformations of the circle. We find a generic increase in the power output with deformation which is relatively insensitive to the specific form of the shape deformation. In addition we find strong mode selection in favor of librational modes (including but not solely the bow-tie modes) in the case when the pumping is concentrated near the center of the cavity. These results point towards an explanation of the dramatic results on power increase with deformation obtained by Gmachl et al. in quantum cascade micro-cylinder lasers. The sensitivity of the lasing solutions to the nature of the ray dynamics (chaotic, integrable and mixed) will also be analyzed.
