← ScienceWhich risk increases when a semiconductor laser's active region is pushed to higher carrier injection?
A)Reduced optical pumping efficiency
B)Increased Auger recombination losses✓
C)Spatial hole burning reduction
D)Enhanced stimulated emission rate
💡 Explanation
Increased carrier density raises the rate of nonradiative Auger recombination because it requires three carriers to interact, therefore energy is lost to heat rather than light; rather than stimulated emission being favored, the efficiency drops significantly due to bandwidth limits.
