Abstract

We consider polarization-squeezed (PS) light generation in anisotropic Kerr medium. The fluctuations of the Stokes parameter either S 2 or S 3 are suppressed in PS light. We show the possibility to transform PS light into light with sub-Poissonian statistics by linear conversion (phase plate and analyser). The quantum properties of the second harmonic (SH) generated by frequency doubling of the PS light are investigated.

Polarization-squeezed light: generation, effects of partial polarization, and linear and nonlinear conversion

Anatoliy S. Chirkin, Natalia Korolkova

We consider polarization-squeezed (PS) light generation in anisotropic homogeneous Kerr medium. The fluctuations of the Stokes parameter either S2 or S3 are suppressed in PS light. The influence of initial light depolarization on the fluctuation suppression of the Stokes parameters is analyzed. We show the possibility to transform PS light into light with sub-Poissonian statistics by linear conversion (phase plate and analyzer). The quantum properties of the SH generated by frequency doubling of the PS light are investigated.

Polarization-squeezed light formation in a medium with electronic Kerr nonlinearity

Florentin Popescu

We analyze the formation of polarization-squeezed light in a medium with electronic Kerr nonlinearity. Quantum Stokes parameters are considered and the spectra of their quantum fluctuations are investigated. It is established that the frequency at which the suppression of quantum fluctuations is the greatest can be controlled by adjusting the linear phase difference between pulses. We shown that by varying the intensity or the nonlinear phase shift per photon for one pulse, one can effectively control the suppression of quantum fluctuations of the quantum Stokes parameters.

Two-mode interactions in DFB systems: polarization-squeezed light and QND measurements

A. P. Alodjants, Sergei M Arakelyan, Anatoliy S. Chirkin

The possibility of formation of polarization-squeezed light in the case of the interaction of two orthogonally polarized waves in the spatio-periodical Kerr medium is considered. It is shown that at the output of such a nonlinear medium fluctuations of one of the Stokes parameter can be less than ones incoherent state. For the first time a procedure of quantum nondemolition measurement (QND) of the Stokes parameters of light is offered and analyzed.

Polarization squeezed light formation in a nonlinear medium with electronic Kerr nonlinearity

Florentin Popescu

A consistent quantum theory of polarization squeezed light formation in a inertial nonlinear medium is developed taking into account the response time of electronic Kerr nonlinearity. Stokes parameters are considered and their fluctuations spectra are investigated. It is established that the frequency at which the suppression of quantum fluctuations of Stokes parameters is the greatest can be controlled by adjusting the linear phase difference between pulses. It is shown that by varying both the intensity and the nonlinear phase shift per photon for one pulse one can effectively control the suppression of quantum fluctuations of Stokes parameters.

Formation of polarisation-squeezed light in type II optical frequency doubling

V. N. Beskrovnyi, Anatolii S Chirkin

A new efficient method for the generation of light with a nonclassical polarisation state is proposed. This method is based on second-harmonic generation by mixing the fundamental-frequency radiation with ordinary and extraordinary polarisations in a quadratically nonlinear crystal. It is shown that fundamental-frequency radiation with strongly suppressed quantum fluctuations of the Stokes parameters can be obtained at the output from this crystal.

Influence of Dissipation Effects on Polarization-Squeezed Light Formation at Frequency Doubling

V. V. Volokhovskii, A. S. Chirkin

The influence of losses and thermal noise on the polarization-squeezed light formation in type II second harmonic generation process has been analysed. New analysis method based on delta-correlation noise properties permitting to calculate correlated and noncorrelated parts of system operators with reservoir ones was employed. Mean values and variances of the Stokes parameter of the light have been calculated.
