    Low Frequency Noise Characteristics of Multimode and Singlemode Laser Diodes 137 in the device structure. In optical fluctuatio ns shot noise with white spectrum prevails 1/ f - type fluctuations at higher frequencies (above 10 kHz). Optical shot noise is caused by the random photon em ission process.
