Instability of linearly polarized lasing modes of a single-mode VCSEL

The full quantum-statistical theory of the Vertical-Cavity Surface-Emitting Laser (VCSEL) in the form of the Langevin equations is constructed for arbitrary relations between the frequency parameters. The same theoretical treatment as in Ref. [1,2] are used. For detailed analysis the theory is applied for lasers with equally living laser levels and on this basis the analytical expressions for the spectral densities of the Stokes parameter fluctuations are obtained in the explicit dependence on the physical phenomena, including the spin-flip and the optical anisotropy. It is demonstrated the arbitrary distribution of electrons between the sub-levels under pumping does not restrict a possibility to achieve the noise reduction below the quantum limit. Under comparison with phenomenological treatment Ref. [3] it is shown this approach turns out to be not quite satisfied.

“…The stability analysis of these stationary solutions was performed in a number of publications, as for example, Refs. [16,17], and we refer the reader to this papers for details. In our analysis of quantum fluctuations we shall assume that the corresponding stationary operation regime of VCSEL is stable.…”

We further elaborate the theory of quantum fluctuations in vertical-cavity surfaceemitting lasers (VCSELs), developed in Ref. [1]. In particular, we introduce the quantum Stokes parameters to describe the quantum self-and cross-correlations between two polarization components of the electromagnetic field generated by this type of lasers. We calculate analytically the fluctuation spectra of these parameters and discuss experiments in which they can be measured. We demonstrate that in certain situations VCSELs can exhibit polarization squeezing over some range of spectral frequencies. This polarization squeezing has its origin in sub-Poissonian pumping statistics of the active laser medium.

Here we demonstrate that photocurrent noise reduction below the standard quantum limit and modal anticorrelation can arise in two mode coupled two-VECSEL system with common pump. This effect occurs due to correlated loss of laser modes. It is possible to suppress noise below the standard quantum limit even for Poissonian coherent pumping, whereas the regularity of the pump can be harmful for non-classicality.
