    "abstract": "We further elaborate the theory of quantum fluctuations in vertical-cavity\nsurface-emitting lasers (VCSELs), developed in Ref. \\cite{Hermier02}. In\nparticular, we introduce the quantum Stokes parameters to describe the quantum\nself- and cross-correlations between two polarization components of the\nelectromagnetic field generated by this type of lasers. We calculate\nanalytically the fluctuation spectra of these parameters and discuss\nexperiments in which they can be measured. We demonstrate that in certain\nsituations VCSELs can exhibit polarization squeezing over some range of\nspectral frequencies. This polarization squeezing has its origin in\nsub-Poissonian pumping statistics of the active laser medium.",
