The propagation of quantized electromagnetic fields through optically isotropic media with cubic optical nonlinearity is considered. Analytical solutions are presented in closed form showing that the light field can emerge from the medium in a squeezed quantum state. A detailed numerical analysis of the results is performed and presented graphically. Over 90 per cent of the squeezing permitted by quantum-mechanical theory is achieved in this way. The dependence of the squeezing effect on the polarization state of the field and the nonlinear molecular parameters is also discussed.

A new mechanism for producing squeezed states in the third-harmonic field generated in isotropic media is discussed. It is shown that considerable squeezing is obtained if the third-harmonic field is generated by self-squeezed light resulting from a nonlinear propagation process. Analytical formulas describing this novel way of producing squeezed states are derived and illustrated graphically, showing strong correlations of squeezing in the fundamental and the third-harmonic beams.

The nonlinear interaction of elliptically polarized counter-propagating waves in an isotropic transparent medium is analysed. Self-induced changes in the polarization of the counter-propagating light waves, are described. Using these results, a new type of modulator giving self-induced rotation of the polarization ellipse (SIRPE) is studied. The transmission of counter-propagating waves in the SIRPE modulator is shown to exhibit saturation with increase in light intensity and to be a multiple-valued function of the light intensity.
