Grating-surface emission from phase-locked monolithic pairs of grating-surface-emitting diode lasers has been observed for the first time. Near-diffraction-limited far fields of 0.06°, spectra and power versus current plots of the coherent emission from the three second-order distributed Bragg reflectors which form the laser cavity for two collinear gain sections are presented. The results suggest that linear arrays of grating-surface emitters can be formed by connecting additional gain-grating sections in series.
