← TechnologyWhich risk significantly increases when excessive optical power enters photodiode?
A)Increased photodiode saturation✓
B)Reduced electromagnetic interference
C)Improved signal-to-noise ratio
D)Decreased thermal expansion
💡 Explanation
Excessive power causes photodiode saturation because the charge carriers cannot be swept out quickly enough leading to a distorted output. Therefore, photodiode saturation is the effect, rather than improved SNR, which would be optimal at moderate operating power.
