A class of laser designs based on one- (1D) and two-dimensional (2D) photonic crystals is proposed which results in surface emitting lasers with a fabrication process similar to that used in edge-emitting distributed feedback lasers. The basic principle is based on a recent discovery that the output coupling characteristics of 2D gratings are significantly different from 1D gratings. In 2D photonic crystals, phase-matching conditions result in the coupling of light to one or a discrete number of directions instead of a cylindrical wave. The lasers are experimentally realized with organic semiconductors and involve photo-excitation of patterned combinations of organic semiconductor and dielectrics.
