Two-dimensional coherent laser arrays are useful for sensing, optical links, laser pumps, and imaging. However, the fabrication procedures necessary for strongly coupled anti-guiding designs are typically complicated and expensive. This work explores a new and much simpler anti-guided array design using ion implantation and photonic crystal confinement in a vertical-cavity surface-emitting laser. The origin of anti-guiding in the laser arrays is described in detail, and
design rules for optimizing performance are discussed. A description of the means to achieve high coherence is presented through both theoretical and experimental investigations. The application of the arrays as low-divergence and steerable sources is demonstrated experimentally
