Theoretical and Experimental Results on GaN-Based Lasers

FIGURE 1 Theoretical prediction (solid lines) and experimental results (triangles) for the gain curve of the nitride laser. 

FIGURE 2 Maximum gain of bulk GaN versus carrier density Bulk GaN has a large gain and a large transparent carrier density

The other problem of current injection is electron overflow [29], The carrier densities shown in FIGURE 4 were simulated for an A1 composition of 0.1 when the bandgap difference between the InGaN well and
