Abstract
The demonstration of two-dimensional arrays of surface-emitting distributed feedback lasers is reported. A 30-element array is shown to produce up to 6.8 W of pulsed output power. A 27-element array bonded on a silicon microchannel water-cooled heat sink is shown to produce as much as 3 W of continuous-wave output power. The high continuous wave power is possible due to the low thermal resistance in the p-side down design of the surface-emitting distributed feedback lasers and effective heat extraction by a silicon microchannel heat sink.Keywords
