We have demonstrated linear and two-dimensional arrays of grating-surface-emitting lasers operating at 1.5 μm. The gain sections are 400-μm-long InGaAs/InGaAsP multiple quantum well ridge-guide diode lasers, connected by waveguide output sections of 300-μm-long distributed-Bragg-reflection gratings. These arrays exhibit coherent, mutual-injection-coupled laser action. The far-field patterns are characteristic of low-order array modes that are nearly diffraction limited. Predominantly single-wavelength-mode operation is observed.
