Which outcome occurs when electrons exceed thermal energy in semiconductor laser cavity?

A)Increased laser gain above threshold
B)Decreased reflective facet transmission
C)Enhanced spontaneous emission spectrum
D)Reduced photon density within structure

💡 Explanation

Increased laser gain occurs because population inversion causes stimulated emission; this Amplified Spontaneous Emission (ASE) depletes electron population. Therefore, gain increases rather than decreasing output, as the system shifts towards lasing rather than other radiative losses.
