Which outcome reduces efficiency when the eigenfunctions overlap in a quantum dot laser?

A)Increased non-radiative recombination losses
B)Enhanced amplified spontaneous emission
C)Decreased differential gain coefficient
D)Suppressed Auger scattering effects

💡 Explanation

Increased non-radiative recombination occurs because increased overlap concentrates electron-hole wave functions, increasing probability of phonon interactions, resulting in heat. Therefore, recombination is the issue; rather than alternatives that involve changes in light emission.
