Intensity of output from semiconductor injection lasers leading to optical intensity noise is due to __________

Intensity of output from semiconductor injection lasers leading to optical intensity noise is due to __________ Correct Answer Fluctuations in amplitude

Fluctuations in the laser output or intensity of laser output leads to optical intensity noise. These fluctuations are generally caused by temperature variations and spontaneous emission in the laser output. This randomness in fluctuations creates a noise source known as relative intensity noise (RIN).
