We have observed lateral electronic beam steering of light emitted by monolithic, two-dimensional, grating-surface-emitting, mutually injection coupled arrays of diode lasers in the AlGaAs/GaAs system. Positionally staggered Y-branch subarrays are optically connected through pumped waveguides which provide the required phase shift. These observations taken in conjunction with previously reported work on steering such arrays in the longitudinal direction now demonstrate, for the first time, monolithic, two-dimensional-coherent-diode-laser arrays that may be electronically steered in two orthogonal directions.
