Abstract :
By measuring the wideband electrical noise voltage at the diode terminal, several laser characteristics can be monitored entirely without optical equipment. The letter describes the application of electrical noise measurements to the study of longitudinal mode hopping and optical feedback-induced noise from, for example, optical fibres.
