Zusammenfassung:In this letter, we present a multiwavelength two-dimensional array based on vertically stacked grating coupled surface-emitting laser bars. The emitters in the array were individually wavelength stabilized using external Littrow gratings fabricated on silicon-based spacers. In pulse operation, lasing with a ~0.3-nm linewidth from each device and maximum total peak power of 120 W was achieved.
