Vertical Cavity Surface Emitting Lasers (VCSELs) are interesting lasers for engineering applications as well as for the study of quantum phenomena. Their quantum noise properties are still under discussion. We present calculations of the performances of VCSELs as squeezed states generator using a semiclassical model for the noise properties of semiconductor lasers. The existence of two polarisation modes P and S is considered using a two‐mode model. The ratio S / P of the power in each polarisation mode is found to be the appropriate parameter to account for the strong influence of polarisation properties on the amplitude noise spectra as well as the correlation between the amplitude fluctuations of the two modes. Either a ratio S / P close to 1 or close to 0 is necessary to get the best squeezing performances. Experimental investigations support these conclusions, showing a strong link between amplitude noise and polarisation properties.
