Description	Low-frequency electrical (laser diode output voltage) and near-field optical (light output power) fluctuation spectra and their cross-correlation factor have been investigated in GaAs/AlGaAs ridge waveguide laser diodes (LDs) with an active region containing a single quantum well (SQW) layer. The noise measurements were performed in the frequency range from 20 Hz to 20 kHz, at dc current ranging from fractions of the threshold current through to multiples of it. It is shown that in the lasing region thee intensive Lorentzian-type electrical and optical noises with negative cross-correlation factor are characteristic for all samples regardless of technological treatments mentioned. This noise is due to charge carrier recombination processes in the interfaces between the active layer and the neighbouring layers.
