Abstract :
The modes and threshold gain characteristics of two-dimensional grating-surface-emitting diode laser arrays that are evanescently coupled in the lateral direction and mutually injection coupled in the longitudinal direction are analyzed. The ratio of the grating transmissivity to reflectivity is found to be a critical parameter in obtaining uniform power distribution inside the array. Good qualitative agreement between the theory and experimentally measured near-field patterns and threshold currents is obtained
