ABSTRACT
A new experimental method is presented to investigate correlations of intensity and phase fluctuations within the spectral bandwidth of one longitudinal mode of a semiconductor laser. This intramode correlation spectroscopy can be applied to study the physical processes which contribute to the linewidth of a semiconductor laser. First results for a GaAs/GaA1As oxide stripe laser reveal the contribution of a low-frequency jitter of the lasing wavelength to the mode linewidth.
